ABSTRACT:
The intensified visual display relates to visual displays which combine generated images with the view of the environment surrounding a user and transmit such combined visual information to the eye position of the user. A fold mirror (1) frequently utilized in such displays reflects only a fraction of the light striking it and, similarly, transmits only a different fraction of the light reaching it. The fold mirror (1) will reflect a maximum amount of light when such light is S polarized and transmit a maximum amount of light when the light is P polarized. If the image generator produces S polarized light, one quarter-wave plate (3) is used to assure that image light to be reflected by the fold mirror (1) is S polarized while image light to be transmitted through the fold mirror (1) is P polarized. If the image generator produces P polarized light, a first quarter-wave plate (31) and a second quarter-wave plate (32) are employed.
