    • A colorimeter capable of calibrating color monitors, whether having cathode ray tube or liquid crystal (LCD) displays, is provided by a photometric array of photodetector and optical filter pairs. The filters include long-pass, edge filters which cover overlapping regions at the upper end of the visible spectrum and a filter which covers the entire visible spectrum. The outputs of the photodetectors are digitally synthesized to provide a response which mimics the response established by the Commission Internationale de 1′Eclairage (CIE) xyz (bar) functions almost perfectly. The response which is mimicked may be represented by the CIE color matching functions. The pairs and the associated components are mounted on a printed circuit board captured in a clamshell housing and having an array of apertures which define angularly constrained fields of view of a surface from which the light, to be colormetrically analyzed, emanates. The printed circuit board includes a field programmable gate array programmed to read data from the plurality of filter/detector pairs in parallel. The colorimeter is capable generally of measuring the color characteristics, especially the color temperatures of radiation radiating and reflecting bodies (sources), including so-called black bodies.

    • A system for measuring deformation of at least one surface of an object including an interferometer for receiving illumination reflected from the surface of the object, and a surface treatment disposed on the surface of the object for providing a retro-reflective patina. The retro-reflective patina is configured to reflect the illumination from the surface of the object. The retro-reflective patina is attached to the surface of the object and may include a plurality of cube corners, or a plurality of dielectric spheres, or a combination of cube corners and dielectric spheres. Impinging light onto the object is provided by an optical source that may be separate from or integral to the interferometer. The impinging light may be directed toward the object through an objective lens, which is also used for receiving the illumination from the object. Alternatively, the impinging light may be directed toward the object by first bypassing the objective lens.

    • A system for measuring distance to an optical surface includes a range finder for transmitting a beam toward the optical surface, and a ring mirror disposed between the range finder and the optical surface. The ring mirror has (a) a circumferential reflecting surface for reflecting a portion of the transmitted beam back to the range finder, and (b) a central aperture for passing another portion of the transmitted beam toward the optical surface. The circumferential reflecting surface is effective in providing a zero reference point for the range finder. The central aperture is effective in passing the transmitted beam to the optical surface for sequentially addressing the optical surface at different locations on the optical surface. The transmitted beam may be steerable for (a) providing the zero reference point circumferentially about the reflecting surface, and (b) providing sequential addresses to locations on the optical surface.
