Zusammenfassung:In this paper, different kinds of methods for realizing gray scale for LCoS were studied. Among these methods, time ratio gray scale (TRG) is superior to other methods in the aspect of gray scale. We have achieved high gray scales and image uniformity for the LCoS using the sub-frame modulation of TRG. In this method, each frame was divided into 8 sub-frames with the proportion as 1:2:4:8:16:32:64:128. Thus totally 256 gray scales was achieved.
