摘要: 用惰性小而廉价的a-Si:H膜作液晶光阀的光导层是一种理想选择。采用阻抗匹配的方法,设计和制作了a-Si:H液晶光阀。在大屏幕投影系统上获得了清晰的投影图象,分辨率为201p/mm。光阀感光度测量表明,写入光在100w,cm2以下,读出光随写入光线性变化。在写入光为100w/cm2时,瞬态响应测量结果为:上升时间60ms,下降时间80ms。

Abstract: It is an ideal selection to use a-Si:H film, which is cheap and with small lag, as the photoconductive layer of liquid crystal light valve. By using the method of impedance matching, an a-Si:H liquid crystal light valve is designed and fabricated, and the clear image on a large screen projective system is obtained. The resolution of the valve is 201p/mm. The sensitometry measurement shows that the projection light level varies linearly with the writing light level when the latter is below 100W/cm2. The measurement of transient response at the writing light level of 100W/cm2 indicates that the rise time is 60ms and the decay time is 80ms. -
