ELECTRO-OPTIC PROJECTION STUDY.

Abstract

This study had as its objective the investigation and evaluation of an image projection technique which utilizes the longitudinal Pockel's effect for light modulation. The light valve tubes used in the study employ an electron beam to develop discrete electric fields through an electro-optic material. These fields induce an optical birefringence in the material which is transformed into proportional intensity modulation of a light beam. Characteristics of two electro-optic materials, potassium dihydrogen phosphate and potassium dideuterium phosphate, were measured in order to optimize the design of the light valve tube. The device was fabricated and demonstrated an ability to project live television imagery. Operating parameters were determined for use in synthesizing an image projection system capable of presenting bright, large scale dynamic displays for command and control applications. (Author)
