  • Automatic transparency masking
    Patent number: 6178672
    Abstract: A method for viewing transparencies comprising backlighting a transparency with polarized light and viewing the transparency through a polarizer. Preferably, the polarization axis of the backlighting and the polarization axis of the polarizer are oriented at about 90 degrees to each other. The transparency is oriented so that a substantial amount of polarized backlighting passes through the transparency and the polarizer. Also disclosed are apparatus for viewing a transparency using polarized backlighting.
