Development Of Optically-Addressed Liquid Crystal Spatial Light Modulators (OA SLM) Operating In Reflective Mode With Diameter 50 Mm Using A-Si:C:H Photoconductors And Nematic And Ferroelectric Liquid Crystals

Abstract

This report results from a contract tasking Research Institute for Laser Physics as follows: The goals of the project are to develop the technology for and master the replication of rewritable holographic devices (optically-addressed liquid crystal spatial light modulators, OA LC SLMs) to be used for real-time correction of optical distortions in imaging optical systems. SLMs using both nematic and ferrroelectric LCs are promising for use as correctors in imaging optical systems. For the SLMs with ferroelectric LCs, high values of refresh rate can me realized (100 Hz and more), together with a relatively high diffraction efficiency (theoretically - up to ~ 40%) for non-polarized reading radiation. The project objectives are to develop OA LC SLMs operating in the reflective mode having a diameter of 50 mm utilizing nematic and ferroelectric LCs, with a clear aperture of 45 mm, an optical quality of better than one quarter of a wavelength, an operating wavelength of 500 to 700 nm, a readout wavelength of 530 nm, and a net optical efficiency of 20% or greater.
