ABSTRACT:
A night vision aid such as night vision goggles (13) is made compatable with a local full color display (17) by blocking local display light from being received by the night vision aid (13). A circular polarizer (23) of one left/right sense is positioned so as to filter the local display. A circular polarizer (25) of an opposite sense is placed before a light input of the night vision aid (13), thereby preventing the polarized light from the display (17) from entering the night vision aid (13). Advantageously, the circular polarizer (23) on the display has minimal effect on linear polarizers which may be used with eyeglasses.
