First Claim
Patent Images
1. A biocular display system comprising:
- a first visual display means which emits light;
a binary optical element means for receiving light from said visual display at a first angle and generating a first virtual image visible to a viewer;
said binary optical element means having magnifying power so that said virtual image appears larger than said visual display means to said viewer; and
said first virtual image being located in space at a distance from said viewer that is longer than the optical path from said viewer to said visual display means.

Abstract
A biocular display system (19) for generating a virtual image (30) of a visible display (20). A diffractive binary optical element (22) is used to create the virtual image (30). The binary optical element (22) contains magnifying power to increase the size of the virtual image (30). Also, the binary optical element (22) contains prismatic power to displace the virtual image (30) away from the display (20). Multiple displays (40), (42) may be viewed by employing a binary optical element (34) having multiple diffractive orders.

13. A biocular display system comprising:
-
a first visual display means for emitting light; a binary optical element means for receiving light from said visual display at a first angle for generating a first virtual image visible to a viewer; said binary optical element means having prismatic power wherein the optical path from said visual display means to said viewer is not coaxial with said optical path from said binary optical element to said viewer; and said first virtual image being located in space at a distance from said viewer that is longer than the optical path from said user to said visual display means. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
