Abstract

Aspects of the present invention relate to providing see-through computer display optics.

Claims

1. An image production optical assembly, comprising:

a light source, wherein the light source is positioned to directly irradiate a segmented surface, wherein the segmented surface includes at least two segments with different reflection properties;

the segmented surface including a first segment that is partially reflective and partially transmissive section and a second segment that is transmissive, the first segment positioned to reflect the light from the light source in a direction to uniformly irradiate a reflective display; and

the second segment positioned to transmit light from the light source such that the light does not irradiate the reflective display.
