USE OF OPTICAL MASERS IN DISPLAYS AND PRINTERS.
Abstract
This report is concerned with further investigations into the digital electro-optic deflector and with results leading to the construction of a model with 256 x 256 output positions. The evaluation of specifications of the deflector was continued. This includes the influence of temperature on the splitting angle between ordinary and extraordinary rays in the birefringent elements. It also includes an analytical evaluation of the influence of fabrication tolerances and bandwidth of light on the background light. Compensation of focal depth into the deflector affects the distribution of background light. The effect is also discussed for various methods of compensation. Birefingent calcite crystals were cemented successfully; results are reported. A lens system for widening the laser beam to the full aperture of the deflector and for focusing the beam to the output plane is specified. Further investigations refer to the problem of electroding the electro-optic crystals. One of the suggested electronic switches for high-speed, low-power operation -- the second harmonic phase modulated switch -- was investigated. The experiments were performed at different speeds and voltages with promising results. (Author)
