OPTICAL CONFIGURATIONS FOR HEAD WORN COMPUTING

1 . A head-worn computer, comprising;

a. an eye imaging camera positioned to capture an image of an eye by capturing light reflected from the eye along an optical axis in the head-worn computer and reflecting off of a plurality of mirrors in an “off” state;

b. a processor transmitting commands to the camera to periodically capture images; and

c. the processor further adapted to permit continued access to a secure computing resource in the event that a comparison of the captured images to a known person's eye image confirms that the known person is wearing the head-worn computer.

2 . The head-worn computer of claim 1 , wherein light reflected off of the plurality of mirrors in an “on” state is directed on an optical axis in-line with the eye of a person wearing the head-worn computer.

3 . The head-worn computer of claim 2 , 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.

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

5 . 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.

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

7 . The head-worn computer of claim 5 , wherein the lighting facility produces a narrow bandwidth of light with a quantum dot illumination facility.

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

9 . The head-worn computer of claim 5 , wherein the lighting facility produces a diffuse cone of light with a backlit illumination facility.

10 . 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.

11 . 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.
