Holographic 3D display using MEMS spatial light modulator

This paper presents a new holographic three-dimensional display technique that increases both viewing zone angle and screen size. In this study, a spatial light modulator (SLM) employing microelectromechanical systems (MEMS) technology is used for high-speed image generation. The images generated by the MEMS SLM are demagnified horizontally and magnified vertically using an anamorphic imaging system. The vertically enlarged images, which are elementary holograms, are aligned horizontally by a galvano scanner. Reconstructed images with a screen size of 4.3 in and a horizontal viewing zone angle of 15° are generated at a frame rate of 60 fps. The reconstructed images are improved by two methods: one reduces blur caused by scan and focus errors, and the other improves grayscale representation. In addition, accommodation responses of eyes to the reconstructed images are explained.
