Total Internal Reflection Modulator/Reflector.
Abstract
This invention relates to a total internal reflection modulator/deflector assembly for use with a beam of polarized incident laser light. The application of a low direct current voltage (e.g., less than 50 volts) to a pair of identical stacked crystals exhibiting the Pockel's effect produces an index of refraction difference at their interface. Since the index changes are small, the incidence angle of the impinging polarized laser light is large, e.g., 89 degrees. In the preferred embodiment, one crystal is rotated relative to the other, such that the applied electric field causes and index changes of + delta n in one crystal and of - delta n in the other crystal.
