Abstract

A projection television is provided comprising at least three image projectors for projecting respective images of different colors onto a holographic projection screen. One of the projectors has a first, shortest optical path disposed in a substantially orthogonal orientation with the holographic projection screen and at least two of the projectors are disposed in adjacent, stepped-relation to one another and have respective optical paths that are (i) selectively defined by the stepped-relation of the projectors; and (ii) converge toward the first optical path in a non-orthogonal orientation so as to define angles of incidence corresponding to a lowest level chromatic aberration of the images by the holographic projection screen. The projection screen is formed by a three dimensional hologram representing a three dimensional array of lenticular elements disposed on a substrate. The screen receives images from the projectors on a first side and displays the images on a second side with controlled light dispersion of all the displayed images.
