Patent abstract

A rear projection display according to the present disclosure includes a complex mirror as an optical element to simplify the optical design. The mirror may be symmetrical about at least one axis to require optimization of only half the optical system. The mirror may also provide a geometrically distorted image that may be corrected in software of the image generator. This display uses a mathematical formulation which inherently creates a surface which is symmetric about one linear axis but free form in an orthogonal axis.
