Abstract:
1. A micro-display engine comprising: an image source for producing a real image; a beamsplitter optically connected to the image source; a pair of reflective optics optically connected in sequence by the beamsplitter for producing an enlargement of the real image as a virtual image that is visible through the beamsplitter, a first optical pathway connects the image source to a first of the pair of reflective optics by one of transmission through and reflection from the beamsplitter, a second optical pathway connects the first reflective optic to a second of the pair of reflective optics by the other of transmission through and reflection from the beamsplitter, a third optical pathway provides for connecting the second reflective optic with a viewing aperture by the one of transmission through and reflection from the beamsplitter.
