利用微机建立了液晶电光效应的控制和探测装置。该装置不仅可以实时、精确、细致地探测液晶的电控双折射效应［１］，而且可以用来研究液晶对外加电压的瞬态响应特性参数。
Using computer to establish the electro-optic effect of liquid crystal control and detection device. The device can not only detect the electronically controlled birefringence effect of the liquid crystal in real time, but also can be used to study the transient response characteristics of the liquid crystal to the applied voltage.
