Abstract:
Apparatus for presenting a plurality of images, the apparatus comprising:a. means for establishing a target zone for a first image; b. means for generating a tracking output image, the output image comprising a first region of light polarized in a first polarization mode and substantially correlated to the target zone, and a second region of light polarized in a second polarization mode distinct from the first polarization mode; c. a display for receiving light from the tracking output image to produce first and second images, each of the images comprising a series of bands, the first-image bands alternating contiguously with the second-image bands; d. means for polarizing light illuminating the first image in a first polarization mode; and e. means for polarizing light illuminating the second image in a second polarization mode, the first and second polarization modes being orthogonal to each other, the light from the tracking output image being directed so as to cause the first image to appear in the target zone and the second image to appear elsewhere.
