  • Patent number: 5838015
    Abstract: A scene projector has spaced-apart optical fibers transmitting electromagnetic radiation by total internal reflection to a like number of spaced-apart absorber structures that are each mounted on the opposite end of one of the optical fibers. The absorber structures absorb the transmitted radiation, convert it to heat, and emit radiation at longer wavelengths, primarily IR. Optionally, a coating having greater emissivity at the longer wavelengths of radiation may be added to the structures to increase radiation at these longer wavelengths. Each optical fiber and absorber structure has a degree of thermal isolation from the adjacent fibers and structures to increase spatial thermal resolution as compared to contemporary monolithic imaging devices. Since the scene projector is optically driven, bulky electronic addressing lines and associated control structure are not needed.
