APPARATUS AND METHOD FOR ACOUSTO-OPTIC CHARACTER GENERATION

摘要

Acoustic energy column segments having predetermined frequencies and representing associated portions of a character are produced in one or more of a set of acoustic energy columns within a body of acousto-optic material in order to form an acoustic energy representation of the character within the body. A pulse of light is flashed through the character representation to create a plurality of diffracted light beams. The diffracted beams are directed to corresponding locations in a character reproduction plane to form an optical representation of the character in the reproduction plane.
