| Abstract;The performance of a 320 * 240 bolometer-type uncooled infrared (IR) detector is described. Vanadium oxide thin film is adopted for the bolometer material, having a sheet resistance of -10k.OMEGA./square. It is patterned so that the bolometer resistance is by a factor of 10 larger than the sheet resistance. This process can increase responsivity. The on-chip readout integrated circuit is designed to reduce signal drift induced by a fluctuation in operation temperature, by referring signals of pixels for which incident IR radiation is not introduced. A thermal image with an NETD (noise equivalent temperature difference) value smaller than 0.1K is shown for F/1 optics and at 60Hz frame rate. (author abst.) |
