Abstract
An extreme off-axis image projection system substantially compensates for image-quality-degrading aberrations typical to off-axis imaging systems. This is accomplished through the use of a free-form mirror in conjunction with both spherical and aspherical refractive elements and an off-axis placement of the input image source. In some embodiments, the off-axis image projection system contains a free-form mirror and a projection lens system with multiple lenses. The projection system projects light from an image source onto a surface (aka, projection surface). The projection surface is both close to the projector (in z) and extends away from the projector (in x and y).
