Abstract:

Integrated optical recording head concepts show promise for future light-weight and compact optical heads. Several fundamental issues remain to be explored before fully integrated optical heads. become a reality. This article reviews the basic operating principles of integrated optic heads, focusing on the materials challenges inherent in developing both partially and fully integrated optical heads.Currently available optical mass storage systems provide a feature unavailable in magnetic direct access storage devices (DASD) — removable and interchangeable media. At present, however, this feature is bought at a price, with magnetic storage devices currently outperforming their optical counterparts in access speed and volumetric storage density. The access time of optical drives is greater than 40 ms, compared to the 10–20 ms typical of magnetic DASD. This is, in large part, a consequence of the 50–100 g moving mass of the optical head. The optical head also limits the maximum volumetric storage density, with current heads ranging from about 0.5 cm to more than 2 cm in height.

Abstract:

Optical laser head is a key component used to shape the laser beam and to deliver higher power laser irradiation onto workpieces for material processing. A focused laser beam size and optical intensity need to be controlled to avoid decreasing beam quality and loss of intensity in laser material processing. This paper reports the multiphysics modeling of an in-house developed laser head for laser-aided additive manufacturing (LAAM) applications. The design of computer experiments (DoCE) combined with the response surface model was used as an efficient design approach to optimize the optical performance of a high power LAAM head. A coupled structural-thermal-optical-performance (STOP) model was developed to evaluate the influence of thermal effects on the optical performance. A number of experiments with different laser powers, laser beam focal plane positions, and environmental settings were designed and simulated using the STOP model for sensitivity analysis. The response models of the optical performance were constructed using DoCE and regression analysis. Based on the response models, optimal design settings were predicted and validated with the simulations. The results show that the proposed design approach is effective in obtaining optimal solutions for optical performance of the laser head in LAAM.

Abstract:

This paper presents a design concept for a head-mounted display, incorporating color stereo vision using commercial LCDs and our own optical relay design. The focus here is on the optical system design, which must meet specifications for a wide field of view, size and cost constraints, and aberration minimization based on human factors. Two multispherical lens systems are presented and compared, one a straight structure and the other a folded structure, which satisfy the design constraints. Their aberrations (distortion, coma, lateral color, field curvature, and astigmatism) have been well corrected, according to human perceptual constraints explicitly discussed. Each has a 20-mm eye relief and an instantaneous field of view greater than 60°; the former has an exit pupil of 10 mm and the latter of 8 mm.

Abstract:

Oral surgery mainly provides surgical scope illumination by doctors wearing headlamps, but there are still clinical restrictions on use. The limitations are (1) due to the angle of the head swing and the shadow of the visual field during the operation and (2) due to projection of the light source being worn on the doctor’s head and the length of the wire, and the fiber-optic wire will affect the relative position of the surgical instrument and limit the scope of the doctor’s activity. This study will focus on the development of oral lighting optical microstructure devices to solve and improve the abovementioned clinical use limitations. The production method is to make an oral lighting mold by 3D printing technology and use the polydimethylsiloxane (PDMS) of liquid silicone material to make an oral lighting device with mold casting technology. The results show that the optical simulation achieves the target light distribution by optimizing the three geometric reflection surfaces combined with the lens design by the optimization method, and the maximum illumination value can reach 5102 lux. According to the measurement results of mold casting technology, the average errors of the profile of the 3D printing finished product and the PDMS finished product of the oral device structure are about 1.4% and 16.9%, respectively. Because the contour of the PDMS finished product’s error caused the light to shift by 0.5∼3 mm distance, the light is still concentrated in the range of the tonsils, so this study can be defined as within the acceptable range of within 16.9% of the intra lighting error. The development of oral lighting devices in this study will reduce the burden on physicians in nonprofessional fields, reduce the time of surgery for patients to maintain the health of doctors, and rise the level of medical equipment to increase surgical safety.

Abstract:

Pole tip recession in magnetic recording thin film heads contributes to spacing loss, which leads to a degradation in the readback signal. As manufacturers improve the performance of magnetic recording devices, this recession will become more significant to the performance of future products. Pole tip recession can be measured by several techniques, including stylus profilometry, optical profilometry, and atomic force microscopy. Stylus profilometry is generally not used since it has several problems in this application. In this study, good correlation was found between optical profilometry and atomic force microscopy measurements, provided that the optical measurements were corrected for phase shift. This is necessary because of the dissimilar materials in the thin film head. There are several methods for making this correction. One method is an analytical correction using known optical constants for the head materials. These constants should be well characterized as the measurements are quite sensitive to them. Overcoating the head with a thin film provides two other methods for getting around the material differences problem. However, these methods require an optimum film thickness. The film must be thick enough so that it behaves as a substrate, but not so thick that it fails to replicate the head. PACS numbers: 85.70.Kh, 06.90. + v, 42.72. + h, 78.65.Pi

Abstract:

Optical head-mounted displays (OHMDs) could support members of emergency medical services in responding to and managing mass casualty incidents. In this contribution, the authors describe the human-centered design of two applications for supporting the triage process as well as the identification of hazardous materials. They were evaluated with members of emergency medical services and civil protection units. In this regard, challenges and approaches to human-computer interaction with OHMDs in crisis response and management are discussed. The conclusion is drawn that often mentioned advantages of OHMDs like hands-free interaction alone will not lead to usable solutions for safety-critical domains. Interaction design needs to be carefully considered right down to the last detail.
