I used a system at CMU which was made by Osaka Gas Information Systems. It used a slide projector as the light source, and a rs232-controlled liquid crystal to generate the stripes. These stripes were then imaged with a BW camera and detected via thresholding. This whole system is commerial - they even sell it with a special processor which signifigantly speed up the processing of the images. hans
