Abstract
Many uses for liquid crystal TV (LCTV) have been reported. An intensity pseudocolor-encoding technique based on the birefringence effect of LCTV under polarized white-light illumination has been demonstrated recently.1 In the new method proposed here, a polarized red light and 90° differently polarized green light are used to illuminate a LCTV. The activated LCTV alters the polarization of the incident light in accordance with the grey level of the video signal. The red and green lights pass through a common analyzer; thus a positive red image and a negative green image are obtained. The superimposition of these positive and negative images produces a pseudocolor image.2
