摘要
利用微机建立了液晶电光效应的控制和探测系统．该系统不仅可以实时、精确、细致地演示和探测液晶的电控双折射效应，而且可以用来研究液晶对外加电压的瞬态响应特性参数．文中提供了液晶光阀在不同波形的驱动电压下的测试结果．
A system controlling and measuring electro-optic effect of liquid crystalsis sctup with computers．With the system，not only electro-birefringenee effect of liquid crystals canbe demonstrated and measured but also transint response parameters on applied voltage can bestudied instantaneously，accurately and finely．The results of measured liquid crystal light valveunder driving voltage of defferent wave shapes are given.
