摘要：

A novel high speed, high contrast, high resolution ferroelectric liquid crystal spatial light modulator using hydrogenated amorphous silicon as a photoconductor (a-Si:H - FLC - SLM) is presented. This device is optically addressed and has good bistability. (1) Response time: Typical values are 500 and 250psec for rise and decay time, respectively. 1μs addressing time is enough to write the spot on the device with a 14mW 780nm laser diode. (2) Contrast ratio: Typically 100: 1 to 150: 1, best result 200:1. (3) Resolution: 60~80LP/mm observed from the USAF resolution test target. Interference fringes with a resolution of more than 120LP/mm are obtained by He -Ne laser. © 1991 Gordon and Breach Science Publishers S.A.
