Cryogenic optical systems are often mounted in vacuum cryostat. An interesting concern in the mechanical design is how to maintain the stability of the line of sight (LOS) of the cryogenic optical system when it is cooled down to very low temperature. To investigate this problem an experimental cryogenic optical system, its mounting structure, and a cryostat were designed and fabricated. After assembling them together, a test experiment for measuring the LOS drift was carried out. Finally, the test results will be presented in this paper.

Recent advances in DNA sequencing techniques require the development of high NA immersion microscope systems with large field-of-view, increased resolution and very tight distortion correction. This paper discusses the opticaldesign and tolerance analysis of a NA 1.0 immersion microscope system with a field of view over 1 mm, which is to be used for four-color fluorescence spectroscopy. The microscope system includes an immersion objective lens and four tube lenses, and is corrected for a wide wavelength range from 490 nm to 712 nm. We will discuss critical aspects of designing this kind of optical system, including special glass selection required for chromatic correction.

Reliable fabrication and assembly of high-quality electro-optical imaging systems is a critical challenge facing electro-optical imaging system manufacturers. optical compensation is one standard approach for minimizing the effects of errors introduced during the manufacture and construction of the optical subsystems. We describe how digital image processing should be considered as a form of compensation when evaluating a complete imaging system. We describe a novel method for digital-optical compensation which jointly adjusts both optical parameters and image processing parameters to maximize end-to-end imaging performance. We verify the superiority of this joint compensation strategy over the traditional sequential compensation through several example imaging systems.

Over the past twenty years numerous papers and patents have reported on the design of infrared zoom lenses for a variety of civilian and military applications. The vast majority of these lenses have been afocal 8-12 mu m zoom lenses with magnification ratios of five to twenty. With the advancement of 3-5 mu m staring focal plane array technology a growing demand has emerged for a compact imaging 3-5 mu m zoom lens. To meet this demand a variety of such zoom lenses have been designed which support image formats of over 10 mm diagonal. In this paper the preliminary design of a high magnification 3-5 mu m zoom lens is described. Infrared system modeling, detailed lens performance and manufacturing issues are reviewed.

The optomechanical engineering for mounting lenses and mirrors in imaging systems is frequently driven by the pointing or jitter requirements for the system. A simple set of rules was developed that allow the engineer to quickly determine the coupling between motion of an optical element and a change in the system line of sight. Examples are shown for cases of lenses, mirrors, and optical subsystems. The derivation of the stationary point for rotation is also provided. Small rotation of the system about this point does not cause image motion.

In this work, two SMS algorithms are presented for an objective design with different selected ray-bundles: three meridian ray-bundles (3M) and one meridian and two skew ray-bundles (1M-2S), the latter from pin hole point of view, provides a better sampling of the phase space. Results obtained with different algorithms will be compared.

An intraocular scattering model was constructed in human eye model and experimentally verified. According to the biometric data, the volumetric scattering in crystalline lens and diffusion at retina fundus were developed. The scattering parameters of cornea, including particle size and obscuration ratio, were varied to make the veiling luminance of the eye model matching the CIE disability glare general formula. By replacing the transparent lens with a cataractous lens, the disability glare curve of cataracts was generated and compared with that of transparent lenses. The MTF of the intraocular scattering model showed nice correspondence with the data measured by a double-pass experiment.

The modern level of development of optoelectronic devices requires the creation of optoelectronic devices, providing maximum information content in different weather conditions, day and night. The solution to this problem is possible only through the creation of optoelectronic devices operating in various ranges of the optical spectrum simultaneously (multi-spectral electro-optical devices). The report presents the results of work on the creation of thermal lenses, working simultaneously in two regions of the spectrum of 3-5 microns and 8-12 microns, shows the results of the specific development of such lenses and their aberration characteristics.
