OPTICAL CONFIGURATIONS FOR HEAD WORN COMPUTING
Aspects of the present invention relate to optical systems in 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. wherein each of the multi-positional mirrors has a first state positioned to reflect illumination light, forming image light, on an optical axis in-line with an eye of a person wearing the head-worn computer; and
c. wherein the optical axis includes, between the image light production facility and the eye of the person, a combiner that reflects a majority of the image light while transmitting a majority of surrounding environment visible light incident on the combiner.
2 . The head-worn computer of claim 1 , wherein the combiner is a holographic mirror 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 , wherein the combiner is a notch mirror 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 , 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.
11 . 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.
