Paper Abstract

The subjects of the study were spatial light modulators (SLM), comprised by polymer photoconductor (PC) or a-Si1-x:Cx:H photoconductor, and ferroelectric liquid crystal. The polymer PC provides the highest available diffraction efficiency (DE) among all layers when the spatial frequency of the hologram exceeds approximately 100 lp/mm. At the same time the parameters of the a-Si1-x:Cx:H PC layer can be varied across the wide range and thus the proper tradeoff between the spatial resolution and reversibly can be chosen.
