报道了用氢化非晶硅（α－Ｓｉ：Ｈ）ｐｉｎ二极管作光敏层，扭曲向列型液晶（ＴＮＬＣ）作电光调制层的光寻址空间光调制器（ＯＡＳＬＭ）的设计、制作与性能测试．结果表明制得的（ＯＡＳＬＭ）分辨率大于２０ｌｐ／ｍｍ；在３００ｌｕｘ白光写入时对比度高于２５：１；白光写入灵敏度约３ｌｕｘ。 The design, fabrication and performance testing of an optical addressable spatial light modulator (OASLM) using hydrogenated amorphous silicon (α-Si: H) pin diodes as the photosensitive layer and twisted nematic liquid crystal (TNLC) . The results showed that the resulting (OASLM) resolution was greater than 20 lp / mm; the contrast was higher than 25: 1 at 300 lux white writing and the white writing sensitivity was about 3 lux.
