TWO STAGE OPTICAL MAGNIFICATION AND IMAGE CORRECTION SYSTEM

摘要

A display (30) having a two-stage optical process is disclosed. This two-stage system enables a relatively compact and inexpensive display. A display screen (38) projects an image that passes through a first lens or lens system. The collimated light is then diffused by one of several methods so as to increase the ultimate viewer's eyebox. The diffused image then undergoes a magnification (32) process involving total internal reflection (34) within a second lens. The light exiting the second lens is magnified to the level desired at a low cost and a small size.
