Liquid crystal optical switching device

摘要: A pair of transparent trapezoidal prisms each having angled endfaces with the larger bases in juxtaposition respect to other forming an interface therebetween are provided at least one optical input and output coupled prisms. Optical radiation is applied normal endface angle greater than critical between liquid crystal beam splitter positioned for splitting which has a shutter respective receive been transmitted or reflected from shutter. Each shutters variable biasing voltage continuous nature selectively controlling passing therethrough thereby controllable switch.
