Optical device
First Claim
1. An optical device for enlarging an eye box, the optical device comprising:
- (a) a first optical expander being carried by, or formed in, a first light-transmissive substrate engaging a first plane; and
(b) a second optical expander being carried by, or formed in, a second light-transmissive substrate engaging a second plane being spaced apart from said first plane;
said first and second optical expanders being designed and configured such that light passing through said first optical expander is expanded in a first dimension, enters said second light-transmissive substrate, through said second optical expander and exits from said second light-transmissive substrate expanded in a second dimension, hence enlarging an eye box of the optical device in both said first and said second dimensions.

Abstract
An optical device for enlarging an eye box, the optical device comprising: (a) a first optical expander being carried by, or formed in, a first light-transmissive substrate engaging a first plane; and (b) a second optical expander being carried by, or formed in, a second light-transmissive substrate engaging a second plane being spaced apart from the first plane. The first and the second optical expanders designed and configured such that light passing through the first optical expander is expanded in a first dimension, enters the second light-transmissive substrate through the second optical expander, and exits from the second light-transmissive substrate, expanded in a second dimension, hence enlarging an eye box of the optical device in both the first and the second dimensions.

43. A method of enlarging an eye box, the method comprising:
-
(a) expanding inputted light rays in a first dimension by passing said light rays through a first optical expander engaging a first plane; and
(b) expanding said inputted light rays in a second dimension by passing said light rays through a second optical expander engaging a second plane being spaced apart from said first plane;
hence enlarging the eye box in both said first and said second dimensions. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87)

88. A method of manufacturing an optical device for enlarging an eye box, the method comprising:
-
(a) positioning a first light-transmissive substrate having a first optical expander carried thereby, or formed therein in a first plane; and
(b) positioning a second light-transmissive substrate having a second optical expander carried thereby, or formed therein, said first and second optical expanders designed and configured such that light passing through said first optical expander is expanded in a first dimension, enters said second light-transmissive substrate, through said second optical expander and exits from said second light-transmissive substrate expanded in a second dimension. - View Dependent Claims (89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 133)

130. An optical device for enlarging an eye box, the optical device comprising:
-
a first light-transmissive substrate engaging a first plane; and
a second light-transmissive substrate engaging a second plane being spaced apart from said first plane;
said first and second light-transmissive substrates designed and configured such that light passing through the device is first expanded in a first dimension within said first light-transmissive substrate, and then expanded in a second dimension within said second light-transmissive substrate, hence enlarging an eye box of the optical device in both said first and said second dimensions. - View Dependent Claims (131, 132, 134, 135, 136, 137, 138, 139, 140, 141)
