摘要： An optically addressed, photoconductive spatial light modulator (SLM) operates in a transmissive mode and is capable of modulating a wide spectrum of visible light. There is no pixel structure or native pixel resolution in the SLM. The SLM has no photodiodes and does not rectify. A light projection system (100) in which one or more SLMs (128, 130, 132) are placed includes a write (image definition) UV light path (102) and a read (illumination) visible light path (104) to form a color image projection display. The write UV light propagates from an image display pattern source (120) and either sequentially or continuously writes image patterns on the photoconductive SLMs. The read visible light propagates through the SLM and is modulated by an electro-optical material, the optical properties of which change in response to the image structure carried by the write light. The result is a high efficiency display system that delivers high resolution color images through a projection lens (190) onto a display screen.
摘要翻译：光学寻址的光导空间光调制器（SLM）以透射模式工作，并且能够调制宽范围的可见光。在SLM中没有像素结构或本机像素分辨率。 SLM没有光电二极管，不能纠正。其中放置一个或多个SLM（128,130,132）的光投射系统（100）包括写入（图像清晰）UV光路（102）和读取（照明）可见光路径（104），以形成彩色图像投影显示。写入UV光从图像显示图案源（120）传播，并且顺序地或连续地将图像图案写在光电导SLM上。读取的可见光通过SLM传播并被电光材料调制，电光材料的光学特性响应于由写入光携带的图像结构而改变。结果是高效率显示系统，其通过投影透镜（190）将高分辨率彩色图像传送到显示屏上。
