SELECTIVE ACCESS LASER DISPLAY BEAM POSITIONER.
Abstract:
The investigation concerns the development of a selective access laser display beam positioner capable of presenting a flexible format and multicolor images on large screen map backgrounds. Basic requirements of the beam positioner are microsecond response and random deflection to any of approximately 1,000,000 resolvable spots. The results of a continuing experimental and theoretical effort toward achieving these objectives are presented. The approach is concentrated on studying the performance characteristics of an iterated electro-optic prism beam angle deflector and on establishing the limits of its resolution capability. It is believed that this type of deflector, augmented by one or two stages of binary-switched lateral beam positioner, will provide maximum optical transmission with minimum driving power. Author
