Feasibility Investigation into the Use of a Liquid Crystal Television as a Spatial Light Modulator

The recent availability of inexpensive, electrically addressable liquid crystal displays has generated interest in the use of such devices for optical processing applications. Characterizations pertinent to this use include: maximum obtainable modulation depth, modulation transfer function (MTF), linearity of response, refresh cycle time and optical flatness. Examples of device performance as a coherent processor and as an incoherent processor will be given
