辐射微热计

Based on the analysis of micro -bolometer resistance -temperature characteristics, a new readout circuit was proposed. It allowed micro -bolometer operate without a temperature stabilizer over a wide range of ambient temperature. And it need a Flash memory to store the correcting factors of different temperatures and a temperature sensor to detect the ambient temperature of the micro -bolometer. By utilizing the factors in the Flash memory, Digital Analog Converter controls the micro -bolometer bias current to compensate the fluctuation of ambient temperature.
