Abstract
Many applications of the liquid crystal television (LCTV) have been reported in literature. By replacing the low-quality polarizers in the LCTV and immersing the LCTV in a liquid gate, a low-cost LCTV can be applied as a spatial light modulator in a real-time optical processor. Applications of the LCTV to white-light signal processing, such as edge enhancement and spatial color encoding, were performed. Real-time pseudocolor encoding based on the birefringent effect of the liquid crystal was also investigated. A pseudocolor encoded image of an x-ray transparency was obtained using the black-and-white LCTV. The white-light noncoherent correlation technique was also studied to overcome the phase variant defect of the LCTV.
