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 adapted to produce a narrow bandwidth of visible illumination light to substantially uniformly illuminate the platform;
c. wherein each of the multi-positional mirrors has a first state positioned to reflect a portion of the illumination light, forming image light, on an optical axis in-line with a partially mirrored surface, wherein the partially mirrored surface includes a patterned reflective portion adapted to reflect the narrow bandwidth of visible light and a transmissive portion adapted to transmit substantially all other bandwidths of visible light; and
d. the mirror positioned at an angle greater than 45 degrees from a front plane of the plurality of multi-positional mirrors wherein the patterned reflective portion is further adapted to reflect a substantial portion of image light directly, without further reflections, towards an eye of a person wearing the head-worn computer.
