Abstract
Abstract A color stereoscopic display system utilizes matrix displays (14, 12), polarized beam combining means (26), and polarization transformation waveplates (30, 38) to present differently circularly polarized left and right images, respectively, in three-dimensional color to an observer wearing circularly polarized glasses (48, 50). <IMAGE>

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
169 words
A stereoscopic display system comprising: a) first display means (14) for emanating a first light beam (34) having a first linear polarization; b) first polarization transformation means (38), proximate to said first display means (14) for transforming the first light beam (34) into a second light beam (36) having a second linear polarization; c) second display means (12) for emanating a third light beam (24) having the first linear polarization; d) polarized beam combining means (26) for passing the second light beam (36) having the second linear polarization and reflecting the third light beam (24) having the first linear polarization thereby resulting in the combining of the second and third beams together in approximately the same direction; and e) second polarization transformation means (30) for transforming the third beam (24, 28) having the first linear polarization into a fourth beam (32) having a first circular polarization and transforming the second beam (36) having the second linear polarization into a fifth beam (40) having a second circular polarization (Fig. 1).
Claim 2
Dependent Claim
139 words
A stereoscopic display system comprising: a) a first display (14) for emanating a first light beam (36) having a first linear polarization; b) a second display (12) for emanating a second light beam (24) having a second linear polarization; c) a polarized beam combining plate (26) for passing the first light beam (36) having the first linear polarization and reflecting the second light beam (24) having the second linear polarization thereby resulting in the combining of the first (36) and second (24, 28) beams together in approximately the same direction; and polarization transformation means (30) for transforming the first beam having the first linear polarization into a third beam (40) having a first circular polarization and transforming the second beam (24, 28) having the second linear polarization into a fourth beam (32) having a second circular polarization (Fig. 2).
