Patent ID: 7002619

Claim:
A system for presenting stereoscopic images for viewing by a person having left and right eyes, comprising: a) means, comprising at least one projector, for projecting (i) a first series of images intended for viewing by the left eye of the person and (ii) a second series of images intended for viewing by the right eye of the person; b) a screen onto which the first and second series of images are projected; c) means, comprising a first linear polarizing filter (i) having a first axis of polarization and (ii) interposed between the at least one projector and the screen, for polarizing the first series of images; d) means, comprising a second linear polarizing filter (i) having a second axis of polarization differing substantially from the first axis of polarization and (ii) interposed between the at least one projector and the screen, for polarizing the second series of images; and e) eyeglasses for wearing by the person and comprising (i) a first lens system associated with the left eye of the person and (ii) a second lens system associated with the right eye of the person, the first lens system comprising: A) a third linear polarizing filter having a third axis of polarization at least substantially parallel to the first axis of polarization; B) a fourth linear polarizing filter (1) interposed between the third linear polarizing filter and the left eye of the person when the eyeglasses are in use and (2) having a fourth axis of polarization differing substantially from the first and third axes of polarization; and C) a first cell interposed between the third and fourth linear polarizing filters; and the second lens system comprising: A) a fifth linear polarizing filter having a fifth axis of polarization at least substantially parallel to the second axis of polarization; B) a sixth linear polarizing filter (1) interposed between the fifth linear polarizing filter and the right eye of the person when the eyeglasses are in use and (2) having a sixth axis of polarization differing substantially from the second and fifth axes of polarization; and C) a second cell interposed between the fifth and sixth linear polarizing filters.
