ABSTRACT:
A stereoscopic imaging assembly for converting true visual images of a real-life subject to a stereoscopic image includes a display and an analyzer. The display is preferably a liquid crystal display, which includes first image pixels, second image pixels, and a polarizer. The first image pixels are responsive to a first electronic image of a first true visual image and the second image pixels are responsive to a second electronic image of a second true visual image. The polarizer has a first polarization material, which enables transmission of light of a first polarity, while blocking light of a second polarity, thereby transmitting a first polarized image having a first polarity. A second polarization material enables transmission of light of the second polarity, while blocking light of the first polarity, thereby transmitting a second polarized image having a second polarity. The analyzer delivers the first polarized image to the first eye of an observer while excluding the second and delivers the second polarized image to the second eye while excluding the first, which enables the observer to synthesize the first and second polarized images into a stereoscopic visual image.
