Comprehensive overview of design requirements and issues in the development of phase-only spatial light modulator (SLM) based liquid crystal on silicon (LCOS) technologies is presented. Phase-only SLMs enable many applications such as holographic three-dimensional (3D) displays, head-up displays for automobiles, laser processing, 3D printers, optical communication, and optical computing. Our LCOS panel can achieve high image quality represented by world-class high contrast ratio. In addition...
