Abstract
A virtual image display system with reduced ambient reflection. The virtual image display system includes a black and white image source for projecting a black and white image. The black and white image is then projected to a magnifying virtual image optical arrangement including a concave reflecting mirror. The magnifying virtual image optical arrangement and a color shutter including a linear polarizer receive the black and white image to generate a magnified color virtual image. The virtual color image display system further includes a .lambda./4-plate for cooperating with the color shutter including the linear polarizer to reduce an ambient reflection from the concave reflecting mirror.
