  • Thermal camera tube
    Patent number: 4097742
    Abstract: A thermal retina disposed in a vacuum envelope receives thermal radiation emitted from an object being viewed includes a semiconductor bolometric thin film target, a metallic heat sink mesh disposed between the thermal radiation and the target to support the target where the heat sink mesh has webs to define web areas of the target and holes surrounded by the webs to define hole areas of the target and a contacting electrode disposed over the holes connecting the film target in the holes to the webs. A readout scanning electron beam is generated in the envelope to provide on the electrode an electric signal proportional to the resistance of the target due to the thermal radiation in the web areas and proportional to the resistance of the target due to the thermal radiation in the hole areas.
