Electro-optical light beam deflector

摘要: A light beam deflector comprises an initial that imparts a small deflection, and deflection amplifier increases the by multiplication factor. The first of two embodiments employs highly-electro-optic-sensitive materials provides methods for reducing eliminating their photorefractive effects, including use suppressing source, external electric fields, temperature control. second embodiment multi-layer, iterative prism structure, increasing aperture without supply voltage. five is Keplerian telescope lens stage negative system stage. Galilean third either or alone. fourth replaces single with compound system. fifth uses special sphere
