Bolometric Sensor with High TCR and Low Resistivity

The invention provides a novel way of operating bolometers in the resistive hysteresis region of a phase-transitioning VO2 film. Background: Visualization of infrared (IR) radiation is achieved by projecting an IR picture onto a sufficiently large 2D matrix of small microbolometers. Using electrical signals, outputs can be visually displayed, thus creating a pixelated image of the original IR picture. One of the issues resolved by the technology relates to the sensor material and its electrical resistance as a function of temperature. Technology Overview: The technology is a bolometric sensor which uses a thin film of vanadium dioxide exhibiting metal-insulator transition qualities, with an arrangement for controlling and regulating the temperature and resistance of a predetermined point, within a main hysteretic loop of the metal-insulator transition. The sensor uses an electronic readout arrangement to monitor the temperature and resistance of the sensor, thus creating a more accurate and longer lasting sensor for visualization.
