The viewing apparatus has video projectors 20a, 20b, for projecting video images of object plane OP. The images are spatially and/or angularly shifted in relation to the object so as to convey parallax between the images. A mirror arrangement such as a concave mirror 35 receives light from the projectors and is located in relation to the projectors such that focussed images of the object are produced at the mirror arrangement. A viewing lens 37 relays exit pupils corresponding to each of the focussed images as reflected by the mirror arrangement to a viewing plane VP so as to be viewable at the respective eyes of the observer as a stereoscopic image without use of adapted eyewear. The video projectors may have video displays 21 and optical arrangements 25 such as lenses 29 and mirrors 31 for focussing light to the mirror arrangement. |
