USE OF OPTICAL MASERS IN DISPLAYS AND PRINTERS.
Abstract
This report describes the design and construction of the peripheral components required for a model of a two-dimensional digital electro-optic flight deflector for 256 x 256 positions. The description of a unit for high-speed switching and modulation includes the effect of the signal of a high-speed electronic switching circuit on the light components transmitted through a KD*P crystal. An electro-optic modulator is used for strobing the light beam. Electronic circuits as well as their mechanical design are discussed. Also discussed in this report are: A beam widener for expanding the laser beam to the aperture of the deflector, the mechanical design of the deflecting system, mounting of the electro-optic and birefringent crystals, and the electrical circuit for push-button control of the deflector. A 60-cps square-wave generator is an optional power supply or control unit. An analysis of power dissipation discusses the problem connected with increased switching speeds. (Author)
