OPTICAL CONFIGURATIONS FOR HEAD WORN COMPUTING
First Claim
Patent Images
1. A head-worn computer, comprising:
- a. an image light production facility including a platform including a plurality of multi-positional mirrors;
b. a lighting facility positioned along a first side of the platform and adapted to produce a cone of illumination light into a solid optic along an optical axis directed away from a front surface of the platform and towards a substantially flat surface of the solid optic that reflects the illumination light such that the front surface of the platform is substantially uniformly illuminated;
c. wherein each of the multi-positional mirrors has an “
on”
state to reflect a portion of the illumination light along a first optical axis that is on-line with an eye of a person wearing the head-worn computer thereby providing bright image pixels and an “
off”
state to reflect a portion of illumination light along a second optical axis off-line with an eye of a person wearing the head-worn computer thereby providing dark image pixels; and
d. an angled surface in the solid optic that transmits bright image pixel light while reflecting dark image pixel light , such that light from the “
off”
state mirrors is redirected toward a second side of the platform, thereby establishing a vertically compact system.
