Characterization of Liquid Crystal Displays for Optical Signal Processing Applications

Abstract

Characterization and analysis of the liquid crystal displays (LCD) used in liquid crystal televisions for possible use as economical spatial light modulators has been performed. This paper presents results of research into LCDs with recommendations for possible applications. This study measured pixel array dimensions; transmission as a function of wavelength, bias voltage, and video voltage; response time; and the optical losses and phase distortion of the LCD. We discuss the usefulness of the LCD as a variable attenuator and as an adaptive wavefront compensator, and ongoing efforts to use the device as a 1-D spatial light modulator in an optical signal processing system.
