A hyperspectral imaging system is proposed for early study of skin diagnosis. A stable and high hyperspectral image quality is important for analysis. Therefore, a light guide sleeve (LGS) was designed for the embedded on a hyperspectral imaging system. It provides a uniform light source on the object plane with the determined distance. Furthermore, it can shield the ambient light from entering the system and increasing noise. For the purpose of producing a uniform light source, the LGS device was designed in the symmetrical double-layered structure. It has light cut structures to adjust distribution of rays between two layers and has the Lambertian surface in the front-end to promote output uniformity. In the simulation of the design, the uniformity of illuminance was about 91.7%. In the measurement of the actual light guide sleeve, the uniformity of illuminance was about 92.5%.

For realization of a miniaturized optical gyroscope the precise assembly of optical micro components is crucial. To detect the rotation rate the laser beam must circulate many times and not leave the resonator due to small misalignments. The assembly of a passive free space triangular ring resonator in which the light can circulate by reflections at three mirrors is investigated. The beam path encloses an area of about 100 mm(2). The resonator shall be activated by an external light source at 1550 nm, a wavelength at which silicon is translucent and allowing to couple light into the resonator through the silicon mirrors. To utilize an inherent mirror alignment two of the mirrors are fabricated with a micro manufacturing process within the same crystal by wet etching resulting in very perfect {111} facets. The etching solution was optimized with respect to process time and smoothness of the mirror surfaces. To further increase the reflectivity of the mirrors different kinds of coatings are tested. With these two perfectly positioned mirrors the assembly challenge reduces to 3DOF alignment of a third {100} mirror for which a well-designed adjustable spacer is developed. In first tests resonance in a linear cavity test setup is demonstrated already.

A multi-band pass filter array was proposed and designed for short wave infrared applications. The central wavelength of the multi-band pass filters are located about 905 nm, 950 nm, 1055 nm and 1550 nm. In the simulation of an optical interference band pass filter, high spectrum performance (high transmittance ratio between the pass band and stop band) relies on (1) the index gap between the selected high/low-index film materials, with a larger gap correlated to higher performance, and (2) sufficient repeated periods of high/low-index thin-film layers. When determining high and low refractive index materials, spectrum performance was improved by increasing repeated periods. Consequently, the total film thickness increases rapidly. In some cases, a thick total film thickness is difficult to process in practice, especially when incorporating photolithography liftoff. Actually the maximal thickness of the photoresist being able to liftoff will bound the total film thickness of the band pass filter. For the application of the short wave infrared with the wavelength range from 900nm to 1700nm, silicone was chosen as a high refractive index material. Different from other dielectric materials used in the visible range, silicone has a higher absorptance in the visible range opposite to higher transmission in the short wave infrared. In other words, designing band pass filters based on silicone as a high refractive index material film could not obtain a better spectrum performance than conventional high index materials like TiO2 or Ta2O5, but also its material cost would reduce about half compared to the total film thickness with the conventional material TiO2. Through the simulation and several experimental trials, the total film thickness below 4 um was practicable and reasonable. The fabrication of the filters was employed a dual electric gun deposition system with ion assisted deposition after the lithography process. Repeating four times of lithography and deposition p

Introduction of coefficients defining the relationship of the radii of curvature of the surfaces of concentric optical systems, allowed the transformation of the obtained analytical relations in a system of two equations with two unknowns. It is shown that the existence of the solution of the system of equations determined by the optical constants of the selected lens material. The results of the analysis of the conditions of the chromatic aberration correction position and the sequence of obtaining of the system equations define the theoretical basis of the engineering method of parametric synthesis of concentric lens systems. Application of the developed method is illustrated by examples of calculation particular systems design build.

This paper presents a methodology for designing an athermalised dual field of view zoom lens in long wave infrared (8 mu m - 12 mu m) spectral band by using the benefits of paraxial optics. By using this design methodology the optical designer can develop many types of complex optical systems in a straightforward way. The key feature of this design methodology relies on utilization of paraxial optics for defining the initial positions of the optical elements. The optical design is based on moving a single lens for changing the optical system's FOV thereby reducing the number of moving parts and simplifying the assembly procedure of the system. The optical design begins with optimization process using paraxial optics. Then the optical design using paraxial optics is used as a template for designing the final optical system by lens material selection for compensating the shift in system's focus due to thermal effects and lens thickness tuning.

The art of lens design has long been divided into two camps: theorists and number crunchers. Both camps have vocal supporters, both manage to get the job done, and both occasionally voice disdain for the other. This paper presents the case for number crunching-while recognizing the important contributions that theorists have made and continue to make. We illustrate this case by designing a zoom lens with no starting design and minimum direction from the designer. To this end we use a feature called ZSEARCH (TM) found in the program SYNOPSYS (TM)(1).

The task of this research project is to define the extent of applicability of such 3D self-manufacture approach to the production of optical fastenings. The resulting lack of equipment, to be used for demonstration of simple experiments, which would be both competitive in performance and cheap to produce, led to the decision to research opportunities for self-manufacturing.

The theoretical basis for the mirror high-aperture optical system synthesis, based on the properties of the reflecting surface accepted as the base having a shape of a paraboloid of rotation are considered in the work design parameters and residual aberrations tables of the few design solutions for considered optical systems are presented. From the analysis of aberration correction of the image formed by the considered optical system, it follows that the angular value image space is limited, primarily, the image surface curvature. To compensate for curvature of the image surface can be applied Smith lens. The additional condition that determines a high aperture ratio of the optical system of the considered lens as a whole was introduced, but it complicates the process of correcting the aberrations of a wide beam of rays. It is shown that the use of afocal Mersenne system with known anaberration properties, allows you to build a series of compact and SLR mirror-lens systems with aplanatic, anastigmatic and plananastigmatic aberration correction formed the image, at the same time the length of the system is about four times smaller than the diameter of its entrance pupil. Importantly, when applying the lens for using in a long wavelength range emission, the requirements for aberration correction image formed by the lens are reduced, and accordingly, manufacturability are increases.
