1. A thinner see-through head-worn computer display, comprising:
an image light production optical module with an upper and a lower portion of the module, wherein the upper module includes a first flat reflective surface arranged to reflect image light produced by an image display, from the upper module to the lower module along a first optical axis, wherein the lower module includes a second flat reflective surface arranged to reflect image light to a user while simultaneously providing the user with a see-through view of a surrounding environment and the reflected image light proceeds along a second optical axis to the user, wherein the upper module is twisted about the first optical axis to change the fit of the optical module into a frame associated with the see-through head-worn computer display and thereby enable the frame to be thinner, and wherein the lower module is twisted a corresponding amount about the second optical axis to introduce a compound angle between the first reflective surface and the second reflective surface to reduce distortion within the image due to the twisting. |
