ABSTRACT OF THE DISCLOSURE An extremely compact multi-image rear view projection system which enables simultaneous oblique angle projection onto a plur- ality of viewing screens without distortion or color loss. The present system is characterized by its structural simplicity which eliminates the necessity for reflecting mirrors behind each screen and, thereby, greatly reduces the viewing cabinet space require- ments. A single light source, together with a plurality of opti- cal systems, each including a collimating lens and a projector lens, may be employed together with a rotating slide transparency carousel so that images may be projected simultaneously upon a plurality of viewing screens.
