Gray level pseudocolor encoding using a liquid crystal television

A real-time gray level intensity pseudocolor encoding method utilizing a liquid crystal television (LCTV) is presented. The LCTV is used under two different polarizer/analyser combinations to generate a positive image and a negative image of an object. The images are also encoded with two different primary colors by positioning the color filters at the two optical paths respectively. The superposition of these images produces a gray level pseudocolor encoded image. Discussions on the properties of the LCTV is provided. Preliminary experimental results are also demonstrated.
