Claim Text:
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 positioned along a side of the platform and adapted to produce polarized illumination light, with a first polarization state, along an optical axis directed away from a front surface of the platform and towards a substantially flat polarized reflective surface that 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 a first state positioned to reflect portions of the illumination light, forming image light, on an optical axis in-line with an eye of a person wearing the head-worn computer; d. a quarter wave retarder positioned over the plurality of multi-positional mirrors and between the substantially flat polarized reflective surface and the platform, so that the polarization state of the image light is opposite of the polarized illumination light, and as a result the image light is transmitted by the substantially flat polarized reflective surface; and e. 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.
