First Claim
Patent Images
1. Wide angle display apparatus comprising:
- a. a first tier comprising one or more narrow angle reflective mirror beamsplitter displays having as one or more inputs aerial images generated by one or more mirror-beamsplitter combinations, said first tier shaped as a first spherical segment bounded on the top and bottom by lines of latitude;
b. 2 second tier comprising one or more narrow angle reflective mirror-beamsplitter displays having as one or more inputs aerial images generated by one or more mirror beamsplitter combinations, said second tier shaped as a spherical segment bounded at the top and bottom by lines of latitude, said bottom line of said second tier having the same angular spacing from the bottom line of said first tier as the top line of said first tier, the centers of said first and second spherical segments being coincident and located so that a plane passing through said center and intersecting the surface of said first tier to form a line of longitude will also intersect the surface of said second tier.

Abstract
An improved wide angle visual display made up of a plurality of narrow angle reflective mirror-beamsplitter displays shaped as spherical segments. By using a second reflective mirrorbeamsplitter combination with each narrow angle display to provide an aerial image input, the field of view of each narrow angle display is increased and thus fewer narror angle displays are required to make a wide angle display of a given size.
