Paper Abstract

The application of Computer- Generated Hologram (CGH) in spatial optical field modulation has greatly promoted the advancement of cutting-edge technologies such as ultra-precise measurement, optical tweezers, super resolution. However, the current processing of CGH is mainly based on microlithography technology. The minimum line width and processing accuracy of CGH have become a crux that limits its further application. In response to the crux, this paper proposes a liquid crystal CGH based on spatial light modulator (SLM) interference exposure method and photoalignment technology, combining the advantages of optical holography and computer-generated holography, aiming at achieving design and fabrication of high precision, maskless, rewritable, sub-micron linewidth liquid crystal CGH. This paper mainly elaborates the principle and design method of the liquid crystal CGH, laying a theoretical foundation for its subsequent widespread application.
