MULTI-COLORED DIELECTRIC COATING
A multi-color dielectric coating is formed using interleaved layers of dielectric material, having alternating refractive index, to create reflections at selected wavelengths, thus appearing as different colors. Etching of selected layers at selected locations changes the color appearance of the etched locations, thus generating a coating having multiple colors. The thicknesses of the layers are chosen such that the path-length differences for reflections from different high-index layers are integer multiples of the wavelength for which the coating is designed.

METHOD FOR FABRICATING A LIQUID-CRYSTAL-BASED ELECTRO-OPTICAL LIGHT MODULATOR USING SURFACE MEMS TECHNIQUES FOR FLAT PANEL DISPLAY INSPECTION
An electro-optic modulator is a liquid-crystal-based electro-optical light modulator. The liquid-crystal-based electro-optical light modulator is fabricated using surface Micro-electromechanical Systems (MEMS) techniques. The electro-optical light modulator is used for inspecting flat panel displays or the like. Utilizing surface MEMS techniques for fabrication considerably thins the electro-optic modulator and allows the use of pure liquid crystal without the need for thick containment plates.
Information display apparatus
The information display apparatus has a housing with an opening and a transparent cover formed on the opening, the housing includes image-light generating means configured to generate image light that displays the image information and an optical system configured to allow a driver of the vehicle to recognize image information based on the image light from the image-light generating means as a virtual image in front of the windshield. When S-polarized light on the windshield is assumed to be a first polarized wave while polarized light that orthogonally crosses the S-polarized light in a polarizing direction is assumed to be a second polarized wave, the image-light generating means is configured to generate the image light made of the first polarized wave, and a transmittance/reflectance control means blocks a part of the first polarized wave and the second polarized wave of incident external light entering the housing from the opening.
