Abstract:
Based on the principle of passive optical athermalization, a wide field medium wave infrared optical system is designed for working at -40℃-60℃. A 320×240 focal plane array (FPA) detector as image plane is used in the system. The system has a field-of-view of 30°×22.72° and a relative aperture of f/2 at 3-5 µm with 100% cold shield efficiency. The modulation transfer function (MTF) of each field is greater than 0.6 at the Nyquist frequency and the maximum distortion is less than 3% at -40℃-60℃. The system can meet the demand of the excellent image quality. This work is valuable for athermaliza

Abstract:
This paper investigates the possibility of passive athermalization of objectives for the long-wave infrared (LWIR) region of the spectrum. The main scientific problem is the difficulty in designing an athermalized objectives without the use of aspherical and diffractive surfaces and with the availability of a limited number of optical materials. A design methodology is applied, the focus of which is the use of materials with a negative thermal coefficient of refractive index and with specific values ​​of the refractive index and Abbe number. The results obtained show that the designed objectiv

Abstract:
IR optical system is much more appropriate to be applied in cluttered and formidable conditions. The change of temperature could degrade image quality of the infrared optical system. So the athermalization becomes the difficult part and key factor in the designing of MWIR optical systems for working under temperature range of -40°C~60°C. In this paper, the infrared telephoto lens is designed; it meets the designing requirements and has good image quality. The effective focal length is 240mm and the F-number is 2.The full field of view is 3.2°. In order to balance the chromatic aberration, an a

Abstract:
Using the example of the development of two simple dual-band monofocal IR objectives, approaches to the layout and design of their optical schemes are demonstrated, depending on whether compensation for the effects of temperature changes on the optical characteristics of these lenses is required or not. It is shown that in the case when thermal compensation is not required, superior optical characteristics can be achieved in a simple triplet, in which the flat surface of the frontal fractional lens carries a diffractive microstructure. In the case of passive athermalization, the optical scheme

Abstract:
A stabilized laser is essential for optical fiber communication network. One of the passive technique for stabilization of central wavelength of laser is based on the application of fiber Bragg gratings. Due to the positive coefficient of thermal expansion of optical fiber, the Bragg gratings within the fiber written by excimer laser gives about 0.01nm/oC shift on the central wavelength respect to the ambient temperature which leads serious problem in the communication network. Since both the temperature and tension force are linearly proportional to the central wavelength of fiber Bragg grati

Abstract:
The use of airborne-mapping technology plays a key role in the acquisition of large-scale basic geographic data information, especially in various important civil/military-mapping missions. However, most airborne-mapping cameras are limited by parameters, such as the flight altitude, working-environment temperature, and so on. To solve this problem, in this paper, we designed a panchromatic wide-spectrum optical system with a focusing function. Based on the catadioptric optical structure, the optical system approached a telecentric optical structure. Sharp images at different object distances
