BROADBAND LASER DISPLAY SYSTEM.
Abstract
This is the first progress report of a series describing the in-house design, fabrication, and evaluation of a Broadband Laser Beam Digital Deflector Display System. The model will be a flexible breadboard assembly which will be used to evaluate and demonstrate 'broadband' or multi-color, laser beam deflection and display techniques. The output of the deflector will be 1024 discrete output light beam positions in each of two dimensions totaling over one million discrete locations. The color and the discrete position of the output beam will be controlled by conventional digital logic circuits. A primary advantage of this multi-color display system is the precise position registration of the small diameter, less than 50 micron, output light beam. General system design guidelines based upon previous external contractual study are presented. Use and extrapolation of these guidelines to determine optical crystal specifications for use in the breadboard deflector are described. A preliminary mechanical model of a split-angle deflector and a two-stage total internal reflection deflector have been designed and fabricated during this reporting period. Laboratory test and evaluation of the electro-conductive substrates for the electro-optic switch assembly are presented. Test procedures, results, and evaluation of small aperature electro-optic modulators for color beam selection are included. (Author)
