Abstract
A wearable display system, such as a Head Mounted Display, having a display engine producing light, preferably linearly polarized light, which defines a synthetic image that is relayed to a wire grid polarizing combiner which overlays the synthetic image onto a real image of an object of the outside world, and wherein the real image is contemporaneously viewed through the wire grid polarizing combiner by the wearer of the system. The wire grid polarizing combiner can be curved in at least one axis, and preferably two axis such that optical power is added to the wire grid polarizing combiner.

57. A method of combining a synthetic image with a contemporaneously viewable real image in a wearable display device, said method comprising:
-
a. producing light representative of a synthetic image;
b. relaying said light to a wire grid polarizing combiner;
c. reflecting at least a portion of said light toward said polarized combiner, said reflected portion of light representative of said synthetic image; and
d. contemporaneously imaging said real image through said wire grid polarizing combiner, such that said synthetic image is overlaid onto said real image. - View Dependent Claims (58, 59, 60, 61)
