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 corresponding to pixels in an image;

b. a lighting facility positioned along a side of the platform and adapted to produce a cone of illumination light along an optical axis directed away from a front surface of the platform and towards a substantially flat surface that substantially 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. wherein the second optical axis terminates with a light suppression facility adapted to prevent light incident onto the light suppression facility from reaching the eye of the person.

2 . The head-worn computer of claim 1 , further comprising:

a. A holographic mirror in-line with the optical axis in-line with the eye of the person wearing the head-worn computer and positioned on an angle with respect to a front surface of the platform to reflect the image light directly, without further reflections, towards the eye of the person wearing the head-worn computer.

3 . The head-worn computer of claim 2 , wherein the angle is greater than 45 degrees.

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

5 . The head-worn computer of claim 4 , wherein the holographic mirror transmits a majority of surrounding environment light incident on the holographic mirror.

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

7 . The head-worn computer of claim 4 , wherein the lighting facility produces a narrow bandwidth of light with a light emitting diode lighting facility.

8 . The head-worn computer of claim 4 , wherein the lighting facility produces a diffuse cone of light with a backlit illumination facility.

9 . The head-worn computer of claim 1 , further comprising:

a. A notch mirror in-line with the optical axis in-line with the eye of the person wearing the head-worn computer and positioned on an angle with respect to a front surface of the platform to reflect the image light directly towards the eye of the person wearing the head-worn computer.

10 . 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.
