Abstract
A liquid crystal light modulator is constructed for the transmission of sch signals modulated onto a light carrier passing through gaseous, liquid, and solid media such as air, water, or glass. A large surface area modulation of the light is accomplished in the visible and infrared range over narrow, however adjustable, wave length ranges or widths. Several circuit arrangements for such modulators are disclosed and their function described.
