Abstract: The invention features a volumetric display system. A light beam representing an image is provided from a stationary source. A projection screen is rotated, relative to the stationary source, about a rotation axis. The light beam is projected onto the projection screen at a non-normal angle of incidence. The light beam is manipulated to reduce distortion in the image caused by projection of the light beam onto the projection screen.

Abstract: In general, in one aspect, the invention features an optical system which forms a light field by providing components of the light field in a series of frames to an image space. The optical system includes a spatial light modulator, a projection lens assembly configured to image the spatial light modulator to the image space for each of a plurality of optical paths, and a scanning optical component configured to direct light from the spatial light modulator through the projection lens to the image space, wherein during operation the scanning optical component directs light corresponding to successive frames along each of the plurality of optical paths through the projection lens assembly.

Abstract: An image scanning assembly comprising at least two optics wherein at least one of the optics is movable relative to the other. An embodiment may be used to scan images for a 3D display.

Abstract: In general, in one aspect, the invention features systems that include a spatial light modulator, a scanning optical component configured to direct light from the spatial light modulator along a plurality of different paths, a projection optical assembly including a plurality of projection lens modules corresponding to the plurality of different paths, wherein each projection lens module is configured to receive light from the spatial light modulator directed along the corresponding path and projects an image of the spatial light modulator to a common image space.
