OPTICAL CONFIGURATIONS FOR HEAD WORN COMPUTING

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 notch mirror;

d. the notch mirror adapted to reflect a substantial portion of the narrow bandwidth of the image light directly, without further reflections, towards an eye of a person wearing the head-worn computer; and

e. the notch mirror adapted to transmit substantially all visible spectrum light other than the narrow bandwidth of the image light to provide high transmissivity of light from a surrounding environment.

2 . The head-worn computer of claim 1 , wherein the notch mirror is adapted to reflect a plurality of visible bandwidths of light and transmit substantially all other visible light bandwidths other than the plurality of reflected visible bandwidths of light.

3 . The head-worn computer of claim 2 , wherein the notch mirror transmits a majority of surrounding environment light incident on the notch mirror.

4 . The head-worn computer of claim 2 , wherein the lighting facility produces a narrow bandwidth of light with a quantum dot illumination facility.

5 . The head-worn computer of claim 2 , wherein the lighting facility produces a narrow bandwidth of light with a light emitting diode lighting facility.

6 . The head-worn computer of claim 2 , wherein the lighting facility produces a diffuse cone of light with a backlit illumination facility.

7 . The head-worn computer of claim 1 , wherein each of the multi-positional mirrors have a second state positioned to reflect portions of the illumination light on an optical axis off-line with the eye of the person wearing the head-worn computer, wherein the off-line optical axis terminates at a light absorption facility.

8 . The head-worn computer of claim 7 , further comprising a solid optic positioned to redirect the off line optical axis to a position proximate a second side of the platform, creating a vertically compact head-worn computer.

9 . The head-worn computer of claim 1 , further comprising an eye imaging camera positioned to image the eye of the person wearing the head-worn computer by capturing light reflected off a subset of the plurality of mirrors wherein the subset of the plurality of mirrors are in a second state.
