Abstract

Due to the small pixel sizes of modern LC-based microdisplays the crosstalk between adjacent pixels has to be taken into account when considering the performance of LCDs used as spatial light modulators in optical setups. This crosstalk effect is called fringing field effect. Measurements show that this effect is anisotropic and therefore has different influences on the diffraction efficiencies of vertical and horizontal gratings. Because such microdisplays are employed in many different holographic applications it is desirable to improve the diffraction efficiency as much as possible. Recently a simulation model of an LCD which takes the fringing field effect into account has been presented. Using this model optimization of blazed gratings is realized to improve the diffraction efficiency.
