Optical system for video projector for moving 3-dimensional stereo images

摘要

The optical system has a projection surface which is reflective to polarised light, which can be viewed through polarisation spectacles. Stereo image pairs are projected on to the surface via the video projector (1), a pair of rotary mirrors (2) a stationary mirror (3) with two relatively angled mirror surfaces and a pair of polarisation filters (4) with perpendicular polarisation planes. Preferably the stereo images are generated by a graphic software programme, an on-line graphic work station, or a video cassette.
