A retinal scanning display with a wavefront curvature modulator

Mitsuyoshi Watanabe; Haruhisa Takayama; Nobuaki Asai; Riki Matsuda; Shoji Yamada

A retinal scanning display with a wavefront curvature modulator (WCM) has been developed and demonstrated. The WCM dynamically modulates the divergence of laser beams to produce multiple focal planes in synchronization with 2-D laser scanning. The produced images have given real stereoscopic feelings to observers because two focal planes are created in a frame. In addition, a motion parallax has been also observed. It has greatly emphasized stereoscopic effects.
