Abstract
This invention relates generally to improved approaches for displaying volumetric three-dimensional (3D) images. The basic idea features improved optical-mechanical mechanisms enabling creation of volumetric 3D images by successive projection of whole frames of 2D images, through an optical-mechanical image delivery system, onto a display plane that moves periodically and sweeps a space. In the rotating approach, two image delivery mechanisms can be used: a revolving multi-mirror system and a revolving orthogonal switchable reflector system. In the reciprocating approach, the image delivery mechanisms include a reciprocating reflector system and a zooming optics.
