Geometric parameters such as fill-factor, pixel shape, and array symmetry strongly affect the performance of membrane light modulators. A set of modeling tools that allow device performance evaluation as a function of these parameters have been developed. The models predict the effect of varying a given parameter and allow visualization of the result. The current modeling results are in good agreement with experimental observation and have formed the basis for computer-aided design of future generations of such devices.

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.
A method of investigation of the optical properties of anisotropic materials using modulation of tho light polarization is presented. Measuring set-up was constructed and used to examine tho optical properties of inte...

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 author proposes a new noise power-spectrum estimation method for mark-dimension fluctuation in optical disks. Diffraction by marks was modeled using Fraunhofer diffraction theory, and mark-dimension fluctuations were taken into account through statistical averaging. The calculated and experimental results agreed well. Fluctuations in the mark edge position mainly contributed to noise.
