Optically addressed liquid crystal light modulators containing photoconductive polymers were investigated in various recording regimes in projection or holographic schemes. Electrically controlled birefringence, optical activity, cholesteric-nematic phase transition, dynamic scattering, and scattering in polymer dispersed liquid crystals were used for light modulation. The best results obtained for the pulse recording holographic regime are the following: limiting resolution up to 1500 mm-1, sensitivity 10-8 J/cm2%, and diffraction efficiency 36%. All modulators can be used in optical information processing, holography, and so on.
