No. 08/152,213 filed Nov. 12, 1993, which is a Division of Ser. No. 07/832,237, filed Feb. 7, 1992, now U.S. Pat. No. 5,303,085.
	Family:			Show 31 known family members
	First Claim: Show all 2 claims			What is claimed is: 1. Transmissive head-mounted on-axis display apparatus for a user, comprising: an image generator which outputs image light, said image generator defining an output plane; a first partially reflective mirror positioned to receive image light from the image generator and to reflect at least a first portion of said image light in a first direction, wherein said image light impinges said first mirror at an angle of between about 40° and about 50°; a second partially transmissive mirror defining a mirror centroid situated to receive at least some of said first portion of said image light from said first mirror and reflect at least a second portion of said image light combined with environmental light, to provide combined light, a tangent plane of said second partially transmissive mirror, at said centroid, positioned at an angle of between about 85° and about 95° with respect to said output plane of said image generator, wherein at least some of said combined light is transmitted through said first mirror in a second direction for ultimate transmission to the eye position of the user, providing an optical path from said image generator to said first mirror, to said second mirror, through said first mirror and to said eye position of the user.
