摘要： A rewritable, heat sensitive, color image recording medium having a pair of opposed substrate sheets at least one of which is transparent, and a heat sensitive layer interposed between the substrate sheets and containing a cholesteric liquid crystal compound having a molecular weight of not greater than 2,000 and a glass transition point of at least 35° C. A color image is formed on the recording medium by varying imagewise the temperature of the heat sensitive layer from a first temperature to a second temperature such that the cholesteric liquid crystal compound assumes a cholesteric liquid crystal phase at at least one of the first and second temperatures. The image is fixed by rapidly cooling the recording medium to a temperature lower than the glass transition point of the cholesteric liquid crystal compound.

摘要： An optically addressed, photoconductive spatial light modulator (SLM) operates in a transmissive mode and is capable of modulating a wide spectrum of visible light. There is no pixel structure or native pixel resolution in the SLM. The SLM has no photodiodes and does not rectify. A light projection system (100) in which one or more SLMs (128, 130, 132) are placed includes a write (image definition) UV light path (102) and a read (illumination) visible light path (104) to form a color image projection display. The write UV light propagates from an image display pattern source (120) and either sequentially or continuously writes image patterns on the photoconductive SLMs. The read visible light propagates through the SLM and is modulated by an electro-optical material, the optical properties of which change in response to the image structure carried by the write light. The result is a high efficiency display system that delivers high resolution color images through a projection lens (190) onto a display screen.
