Patent Images

1. An optical system for presenting virtual optical images of an image source outputting light in a forward direction at a desired apparent distance comprising:

  • (a) a first at least partially light transmissive member having a non-uniform transmission characteristic for receiving light from said image source and outputting altered light in a forward direction;

    (b) a partially transparent and partially reflective focusing member receiving said altered light and outputting transmitted altered light; and

    (c) a partially transmissive and partially reflective member for reflecting said transmitted altered light in a rearward direction toward said focusing member, said focusing member having the characteristic of reflecting said reflected transmitted altered light, and said partially transmissive and partially reflective member transmitting reflected transmitted altered light reflected from said partially transparent and partially reflective focusing member.
