Abstract: Disclosed herein are three-dimensional projection systems and related methods employing two electronically controlled projectors and a retro-reflective screen. The retro-reflective screen produces a known non-linear light reflection pattern when images are projected thereon. Image computational means are used to calculating flat image information for each projector based upon inputted stereopair images and information regarding the projectors and screen. In preferred embodiments of the present invention, the projection system uses an image computational device that employs a neural network feedback calculation to calculate the appropriate flat image information and appropriate images to be projected on the screen by the projectors at any given time. More than two projectors can be employed to produce multiple aspect views, to support multiple viewers, and the like. In another embodiment, the projection system includes a digital camera that provides feedback data to the image computational device.

Abstract: Disclosed herein are three-dimensional projection systems and related methods employing liquid crystal display panels and a phase screen to project a true three-dimensional image of an object. Certain embodiments of the projection systems can include an imaging system capable of projecting “amplitude hologram” images onto a phase screen to produce a viewable three-dimensional image. The imaging systems disclosed use at least one liquid crystal display panel, an image generation system for calculating flat image information and for controlling the liquid crystal panels, and a phase screen. The screen has regular “phase” information recorded on it, which can be a known phase-only or phase-plus-amplitude hologram that is not dependent on three-dimensional object to be projected.
