Outline of Final Research Achievements

Although holography is an ideal three-dimensional display technique, the previous techniques require a pixel pitch smaller than one micron and a resolution larger than approximately million × million so they are difficult to be realized. In this study, a completely opposite approach is used; a pixel pitch is enlarged to increase the screen size and a spatial scanning is used to increase the viewing zone. The viewing-zone scanning holography is proposed, which employs the combination of a MEMS-SLM and a Galvano scanner. The multi-channel display system consisted of multiple hologram projectors employing the MEMS-SLMs is also proposed to further increase the screen size. The rotation-type planar scanner is developed to support a large screen size. Moreover, RGB lasers are used to enable the color image generation using the time-multiplexing technique.
