Abstract
A projection television system includes an image source or projector, a projection screen, and at least one mirror positioned so as to reflect an image from the projector to the projection screen, and also to expand the image in at least one of respective first and second mutually transverse planes. The at least one image expanding mirror may be part of a mirror system consisting of simple partially cylindrical mirrors that separately expand the image in the vertical and horizontal planes, or may take the form of a single spherical mirror similar to a wide angle fisheye or truck mirror having image expansion properties in both planes. Alternatively, one or more image expanding mirror may be in the form of, or include, reflective sheets that include image-expanding lenticular surfaces.
