Abstract

The wide range of electro-optical properties such as electrically adjustable optical activity, birefringence and scattering make liquid crystals (LC) suitable for defined alternation of amplitude, phase polarization and spectral composition. Optically and electrically addressable LC-SLM being the data input or light modulating devices result in arrangements which can be used for real-time image processing, holographic applications and optical computing systems. The range of SLM applications is dependent on such parameters as sensitivity, resolution capability, switching time, flatness and thermal-mechanical stability. The parameters of optical addressable a-Si:SLMs, MIS-SLMs, and CdS-SLMs with liquid crystals as light modulating layers and their technological dependence are in discussion.
