Paper Abstract

A 3D volumetric display utilizes the moving screen projection technique with a fast switching spatial light modulator is presented. This technique displays volumetric 3D images by successive projection of whole frames of 2D images, through an optical-mechanical image delivery system, onto a revolving translucent screen. The series of projected 2D images distributed in the space forms a volumetric image because of the after-image effect of human eyes. A ferroelectric liquid crystal spatial light modulator is used as the image source, which enables 256 X 256 X 128 monochrome voxels in the display space. A rotating- reflectors mechanism is used to perform the moving projection function. Methods of processing 3D data and sequencing frame data are developed to integrate the SLM system and the optical-mechanical mechanism.
