Abstract
Abstract Optical simulation apparatus in which three relatively movable images are input to the system. One of the images is produced by a physical display object and the other images are presented on display screens, superimposed by a beam-splitting mirror, and directed to an infinity display system. True apparent distances and relative parallax of the three images are simulated. The simulation is enhanced by tilting elements of the infinity display system and one of the display screens relative to the optical axis of the apparatus.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
174 words
Optical simulation apparatus for training an observer in the manipulation of a controllable real-life element relative to at least one real-life image, said apparatus comprising: (a) optical means for forming an image at or near infinity for stereoscopic viewing by said observer; (b) a first display screen and means for generating a first display of a simulated real-life image on said first display screen; (c) a second display screen and means for generating a second dislay of another simulated real-life image on said second display screen; (d) means for combining images from said first and second display screens and for directing said images toward said optical means for forming an image viewable by said observer; and (e) a three-dimensional physical object positioned between at least one of said display screens and said optical means for forming an image, whereby said physical object is itself directly viewable by said observer with parallax and relative distance relative to said first and second displays, said physical object being a dimensionally smaller model of said controllable real-life element.
Claim 2
Dependent Claim
174 words
Optical simulation apparatus for training an observer in the manipulation of a controllable real-life element relative to at least one real-life image, said apparatus comprising: (a) optical means for forming an image at or near infinity for stereoscopic viewing by said observer; (b) a first display screen and means for generating a first display of a simulated real-life image on said first display screen; (c) a second display screen and means for generating a second dislay of another simulated real-life image on said second display screen; (d) means for combining images from said first and second display screens and for directing said images toward said optical means for forming an image viewable by said observer; and (e) a three-dimensional physical object positioned between at least one of said display screens and said optical means for forming an image, whereby said physical object is itself directly viewable by said observer with parallax and relative distance relative to said first and second displays, said physical object being a dimensionally smaller model of said controllable real-life element.
Claim 3
Dependent Claim
17 words
Optical apparatus according to claim 1 wherein said means for combining images is a beam splitting mirror.
Claim 4
Dependent Claim
