Abstract:
The testing technique with high dynamic range is required to meet the measurement of refractive wavefront with large distortion from test refractive surface. A general deflectometric method based on reverse Hartmann test is proposed to test refractive surfaces. Ray tracing of the modeled testing system is performed to reconstruct the refractive wavefront from test surface, in which computer-aided optimization of system geometry is performed to calibrate the geometrical error. For the refractive wavefront error with RMS 255 mu m, the testing precision better than 0.5 mu m is achieved.

Abstract:
The deflectometry provides a feasible way for surface testing with a high dynamic range, and the calibration is a key issue in the testing. A computer-aided testing method based on reverse Hartmann test, a fringe-illumination deflectometry, is proposed for high-accuracy testing of reflective surfaces. The virtual "null" testing of surface error is achieved based on ray tracing of the modeled test system. Due to the off-axis configuration in the test system, it places ultra-high requirement on the calibration of system geometry. The system modeling error can introduce significant residual systematic error in the testing results, especially in the cases of convex surface and small working distance. A calibration method based on the computer-aided reverse optimization with iterative ray tracing is proposed for the highaccuracy testing of reflective surface. Both the computer simulation and experiments have been carried out to demonstrate the feasibility of the proposed measurement method, and good measurement accuracy has been achieved. The proposed method can achieve the measurement accuracy comparable to the interferometric method, even with the large system geometry calibration error, providing a feasible way to address the uncertainty on the calibration of system geometry.

In the fringe-illumination deflectometry based on reverse-Hartmann-test configuration, ray tracing of the modeled testing system is performed to reconstruct the test surface error. Careful calibration of system geometry is required to achieve high testing accuracy. To realize the high-precision surface testing with reverse Hartmann test, a computer-aided geometrical error calibration method is proposed. The aberrations corresponding to various geometrical errors are studied. With the aberration weights for various geometrical errors, the computer-aided optimization of system geometry with iterative ray tracing is carried out to calibration the geometrical error, and the accuracy in the order of sub-nanometer is achieved.

Abstract:
The Hartmann screen test (HST) is a well-known technique that has been used for many years in optical metrology. This thesis describes how the technique has been adapted to create a system for continuous in situ monitoring of the internal stress in thin films during plasma deposition. Stress is almost always present in thin films. Stress can affect the physical properties of film, and also influence phenomena which are important in the technology of thin film manufacture such as adhesion and crystallographic defects. For these reasons, it is very important to control and manage the film stress during manufacture of devices based on thin films. The commonest way to infer stress is to measure the change in substrate curvature that it produces. This is often done by comparison of substrate curvatures before and after deposition with surface profilometry, or interferometry. However, these methods are unsuitable for implementing during film deposition in the vacuum chamber. A novel method for measuring changes in curvature of the thin film substrate in situ has been developed, making use of the HST. An expanded laser beam is passed through a screen containing a number of small apertures, which breaks it up into several rays. After reflecting from the surface of the thin film wafer, the rays are received on an array detector as a spot pattern. Image processing is performed on the recorded spot images to determine the positions of spots accurately. Spot centre positions are recorded at start of deposition as a reference, then their displacement is tracked with time during deposition. The spot deflections are fitted to a theoretical model, in which the change in sample profile is described by a second-order surface. The principal axes of curvature of this surface and their orientation are obtained by a least-squares fitting procedure. From this, the thin film stress can be inferred and monitored in real time. Equipment using this technique has been designed and developed in prototype form for eventual use in the RMIT cathodic arc deposition facility. First experiments with a classic Hartmann screen configuration proved that the technique gave good results, but precision was limited by diffraction and interference effects in the recorded image which made determination of spot centres more difficult. A modified configuration was developed, in which a camera is focused on the Hartmann screen, giving much sharper spot patterns and improved resolution. Tests on the prototype system and comparison with other techniques have shown that it is possible to determine changes in sample curvature with a precision of approximately 0.01 m-1. This corresponds to stress changes of around 0.5 GPa for typical wafer and film thicknesses used in practice. The Hartmann screen test is straightforward to use and to interpret. Image processing and analysis of the recorded spot patterns can be automated and performed continuously in real time during thin film deposition. The system promises to be very useful for monitoring stress and thus controlling the deposition process for improved quality of thin film manufacture.

Abstract:
The Hartmann-Shack (H-S) wavefront sensor is now deployed in many different fields, from astronomy to industrial inspection, where the quality of optical media or components can be measured by the distortions (wavefront aberrations) they impart on a wavefront transmitted or reflected by them. In ophthalmology, this sensor is a core component of major aberrometers, used in the assessment of the visual quality of the eye, academic research and clinical diagnosis. The H-S wavefront sensor is also found in adaptive optics (AO) systems, which are used to improve the quality and the capabilities of optical systems, by compensating for wavefront aberrations that affect light waves. These image distortions can represent a serious problem in many different applications where high-quality images are demanded. The microlens array is an important element in the H-S sensor, responsible for sampling the aberrated wavefront into light spots on the focal plane. The position of each light spot relates to the average tilt of the wavefront over the respective microlens. These spot­position coordinates are then used in the modal reconstruction to approximate the wavefront topology with a combination of orthogonal basis functions. The wavefront reconstruction error describes the deviation of the reconstructed wavefront from the reference one. The wavefront sampling is influenced by the microlens distribution pattern in the array, lens contour and size, number of microlenses and fill factor. Adopted grids typically consist in either rectangular or hexagonal configurations. The influence of the array geometry on the wavefront reconstruction error was already discussed in the literature, which demonstrated that random arrays might perform better than regular ones. This work proposes the optimization of the microlens-array geometry to be used in a specific context, such as ophthalmology. The workflow consisted of three major steps: numerical optimization, to find the optimal microlens arrays; fabrication of the arrays; and test on an optical bench, to comparatively assess the performance of the fabricated and commercial arrays. The optimization comprises the minimization of the wavefront reconstruction error and/or the number of necessary microlenses in the array, considering a known aberration statistics. Within the ophthalmological context, as a case study, it was demonstrated by the numerical simulations that 10 or 16 suitably located microlenses can be used to produce reconstruction errors as small as those of a 36-microlens rectangular array. The optimized arrays were then fabricated in a clean room, where KOH anisotropic etching was used to obtain the silicon molds from which the microlens arrays were replicated on polymer by casting. Four arrays were fabricated: 10- and 16-microlens optimized arrays and 16 and 36-microlens rectangular arrays. All four arrays were tested and compared to a standard 127-microlens hexagonal commercial array, using an arbitrary wavefront aberration, which is compatible with the used ophthalmological wavefront-aberration statistics. The final results corroborate with the predictions of the computational simulations.
O sensor de frente de ondas de Hartmann-Shack (H-S) é aplicado a diversas áreas do conhecimento, da astronomia à inspeção industrial, em que a qualidade de meios ou componentes ópticos pode ser medida através das distorções (aberrações de frentes de onda) que eles inserem em uma frente de onda, seja por reflexão ou refração. Em oftalmologia, este sensor é um componente central da maioria dos aberrômetros, que são usados na avaliação da qualidade óptica do olho, em pesquisas e em diagnóstico clínico. O sensor de frentes de onda de H-S é também encontrado em sistemas ópticos adaptativos, que são usados para aumentar a qualidade de sistemas ópticos, por meio da compensação de aberrações de frentes de onda. Essas distorções nas frentes de onda podem representar um sério problema em diversas aplicações que requerem imagens de alta qualidade. A matriz de microlentes é um importante elemento no sensor de H-S responsável pela amostragem da frente de onda aberrada em pontos de luz no flano focal. A posição de cada ponto de luz relaciona a inclinação média da parte da frente de onda amostrada pela respectiva microlente. As coordenadas das posições de todos os pontos de luz são usados no processo de reconstrução modal para aproximar a topologia real da frente de onda através de uma combinação de funções ortonormais. O desvio dessa aproximação é chamado de erro de reconstrução. A amostragem da frente de onda é influenciada pelo padrão de distribuição das microlentes na matriz, formato e tamanho das microlentes, número de microlentes e fator de preenchimento da matriz. As matrizes comumente encontradas no mercado possuem, em geral, configura·o retangular ou hexagonal. A influência da geometria da matriz sobre o erro de reconstrução já foi discutido na literatura, que demonstrou que geometrias aleatórias podem apresentar performance melhor do que as geometrias regulares. Este trabalho propôs a otimização da geometria da matriz de microlentes para ser usada em um contexto específico, como oftalmologia. O trabalho consistiu de três fases: optimização numéica, para encontrar as matrizes ótimas; fabricação e teste em bancada óptica, para avaliar comparativamente a performance das matrizes fabricadas e uma matriz comercial. A otimização consiste na minimização do erro de reconstrução e/ou do número de microlentes necessárias na matriz, considerando uma estatística de aberrações conhecida. No contexto oftalmológico, usado como estudo de caso, foi demonstrado pelas simula·es que matrizes otimizadas com 10 ou 16 microlentes podem ser usadas para produzir erros de reconstrução da mesma ordem que matrizes retangulares com 36 microlentes. As matrizes otimizadas foram então fabricadas em uma sala limpa, onde corrosão anisotróica por KOH foi utilizada para obter-se moldes dos quais as microlentes foram replicadas em polímero. Foram fabricadas as matrizes otimizadas com 10 e 16 microlentes e também as matrizes retangulares com 16 e 36 microlentes. Todas as matrizes foram testadas e comparadas com uma matriz hexagonal comercial, com 127 microlentes. Os testes foram feitos com uma aberração arbitrária, mas compatível com a estatística estudada. Os resultados finais corroboram com os previstos pelas simula·es computacionais.

Abstract:
A head-mounted-display with an optical combiner may introduce significant amount of distortion to the real world scene. The ability to accurately model the effects of both 2-dimensional and 3-dimensional distortion introduced by thick optical elements has many uses in the development of head-mounted display systems and applications. For instance, the computer rendering system must be able to accurately model this distortion and provide accurate compensation in the virtual path in order to provide a seamless overlay between the virtual and real world scenes. In this paper, we present a ray tracing method that determines the ray shifts and deviations introduced by a thick optical element giving us the ability to generate correct computation models for rendering a virtual object in 3D space with the appropriate amount of distortion. We also demonstrate how a Hartmann wavefront sensor approach can be used to evaluate the manufacturing errors in a freeform optical element to better predict wavefront distortion. A classic Hartmann mask is used as an inexpensive and easily manufacturable solution for accurate wavefront measurements. This paper further suggests two techniques; by scanning the Hartmann mask laterally to obtain dense sampling and by increasing the view screen distance to the testing aperture, for improving the slope measurement accuracy and resolution. The paper quantifies the improvements of these techniques on measuring both the high and low sloped wavefronts often seen in freeform optical-see-through head-mounted displays. By comparing the measured wavefront to theoretical wavefronts constructed with ray tracing software, we determine the sources of error within the freeform prism. We also present a testing setup capable of measuring off-axis viewing angles to replicate how the system would perform when worn by its user.

Abstract:
Felicitas Hoppe gives an introduction to the art of adapting medieval poetry that is in itself a poetic work. In 2008, Hoppe adapted Hartmann von Aue’s Arthurian romance Iwein into a highly successful young adult novel. She speaks about this experience and about the art of adapting medieval literature more generally: about encountering popular images of knights looking like ladies and about inverted gender roles in Hartmann’s romance; about history as produced by wishes; about finding Iwein by chance in a bookshop and being captivated by its beauty; about the romance’s surprising timelessness in its psychologically astute characterisation, its sensible rationality and its uncompromising morality; about the dialectic between boredom and adventure, between the desire to grow up and the fear of growing up in all good children’s books (and Arthurian romances); about the relationship between honour and masculinity in the romance code of values; about Iwein’s insistence on physicality; and about narrative techniques for modernising the text (including the introduction of Iwein’s companion, the lion, as the narrator). As a whole, Hoppe’s piece is a remarkably sensitive analysis of how and why aspects of medieval literature exert a fascination on creative minds. It compellingly demonstrates the wealth of insights that adaptors of medieval texts gain, which can complement and inspire those of literary critics.

This chapter examines the definitions of the term aventure. It considers this term to be an essential technical term of the medieval poetic vocabulary. It has been recognized as such by modern scholars, who stress the poetological meaning the term acquires in Hartmann von Aue, as well as the performative character the poetic text acquires to the extent that the act of telling and the content of the tale tend to converge. In chivalric poems, Aventure seems to have as many meanings as Tyche. Like Tyche, it designates both chance and destiny: the unexpected event that challenges the knight and a series of facts that will necessarily take place.

Scraps of text on accounting paper on the backs of each figure tell poetically the journey of these people through the change in their names when in the new place. The figures act as a guerrilla memorialisation of multiple African diasporic figures who have been forgotten by history.

Abstract:
Computer science and physics have been closely linked since the birth of modern computing. This book is about that link. John von Neumann’s original design for digital computing in the 1940s was motivated by applications in ballistics and hydrodynamics, and his model still underlies today’s hardware architectures. Within several years of the invention of the first digital computers, the Monte Carlo method was developed, putting these devices to work simulating natural processes using the principles of statistical physics. It is difficult to imagine how computing might have evolved without the physical insights that nurtured it. It is impossible to imagine how physics would have evolved without computation. While digital computers quickly became indispensable, a true theoretical understanding of the efficiency of the computation process did not occur until twenty years later. In 1965, Hartmanis and Stearns [227] as well as Edmonds [139, 140] articulated the notion of computational complexity, categorizing algorithms according to how rapidly their time and space requirements grow with input size. The qualitative distinctions that computational complexity draws between algorithms form the foundation of theoretical computer science. Chief among these distinctions is that of polynomial versus exponential time. A combinatorial problem belongs in the complexity class P (polynomial time) if there exists an algorithm guaranteeing a solution in a computation time, or number of elementary steps of the algorithm, that grows at most polynomially with input size. Loosely speaking, such problems are considered computationally feasible. An example might be sorting a list of n numbers: even a particularly naive and inefficient algorithm for this will run in a number of steps that grows as O(n2), and so sorting is in the class P. A problem belongs in the complexity class NP (non-deterministic polynomial time) if it is merely possible to test, in polynomial time, whether a specific presumed solution is correct. Of course, P ⊆ NP: for any problem whose solution can be found in polynomial time, one can surely verify the validity of a presumed solution in polynomial time.
