The expressions of the Seidel aberration theory are comparatively simple and easy to use due to its characteristics and prerequisites. Meanwhile, the effective range of the theory is limited also due to its prerequisites. The possibility for enlarging its effective range is analyzed in this paper.

A novel concept on the construction of high-resolution objectives is outlined. Although similar to binary optics technology, this approach brings additional degrees of freedom to the opticaldesign as far as achieving a finer balance of phase curvature via refractive properties and relative thickness of the multilayer stack. The differential coating objective can be used in conjunction with diffractive surfaces to optimize the transmission efficiency and control the secondary spectrum correction. The basic equations describing the monochromatic and three- color achromat predesign are presented.

It has been shown that the Admittance Diagram along with the Quarterwave Rule can be used in the design and characterization of optical thin film coatings. However, this same tool may be utilized in the design and characterization of some microwave components as well. A simple design example of a Wilkinson power divider is presented to illustrate the utility of this optical technique for microwave circuit design and analysis.

An application of Fourier transform lenses to surface topography detection is investigated. The field is illuminated in parallel using an array of three different wavelength laser diodes, and relative phase alteration is read out between cross-correlated electronic pixels. Diffraction theory of image formation is used to interpret the modulation in contrast. Speckle sensitivity to wavelength provides the basic technique for noise filtering.

The techniques used for the analysis of thermally induced structural distortions of optical components such as scanning mirrors and telescope optics are outlined. Particular attention is given to the methodology used in the thermal and structural analysis of the GOES scan mirror, the optical analysis using Zernike coefficients, and the optical system performance evaluation. It is pointed out that the use of Zernike coefficients allows an accurate, effective, and simple linkage between thermal/mechanical effects and the opticaldesign.

This paper presents a new idea for the optimization of an initial lens structure type from an optical lens database on the basis of introducing optical lens database (OLDB) and computer- aided opticaldesign (CAOD) systems. Using image-quality target parameters as conditional search parameters of optimization of initial lens structure type from database, and evaluating selected lens quality with surface relative aperture (h/r), the authors were able to obtain a good effectiveness in practice.

The revisions of enlarging all the aberrations related to aperture to the seventh order for the Seidel aberration theory have been proposed in this paper. The practice of the revised theory in the range of small viewing field and large aperture (for example, the lens of microscope and telescope) has proven that the theory is applicable in this scale.

Matrices of optical components (like LEDs, microlenses, microzone plates, microspatial filters) are used in some arrangements to obtain the optical transformation from an area of a frontal plane to a point and vice versa. By use of these matrices the following arrangement are established: a matrix optical relay-system, a multichannel optoelectronic hybrid computer, an optical system for pattern recognition by spatial multichannel filtering, and uniform illumination system. The established relationships are applied to calculate the positions, the component sizes, and the system performance. Matrix configuration is shown to be advantageous for maximizing the performance for plane-point correlation and, also, for a miniature solution.
