HOLOGRAPHICAL PHYSICAL PROJECTION TRANSFER EQUIPMENT WITH OPTICAL CORRECTION

摘要

A projection television (10) is provided that comprises an optical system having at least three image projetors (14, 16, 18) for projecting respective images of different colors onto a projection screen (22), and a holographic reflector (20) disposed in optical communication with the image projectors (14, 16, 18) and the screen (22) so that one (16) of the projectors has a first optical path (32) in a substantially orthogonal orientation with the screen (22) and at least two (14, 18) of the projectors have respective optical paths (34, 36) converging toward the first optical path (32) in a non-orthogonal orientation defining angles of incidence. The projection screen (22) is formed from a three-dimensional hologram (26) representing a three-dimensional array of lenticular elements disposed on a substrate (24). The screen receives images from the projectors (14, 16, 18) on a first side and displaying the images on a second side with controlled light dispersion of all the displayed images.
