Method and apparatus for readout of compound microbolometer arrays

The method and equipment in the picture which the micro bolometer array which consists of two or more small arrays generates which reduce the deficit which is not desirable, While supplying an individual bias pulse to each micro bolometer of a small array, the signal produced as a result which receives the bias pulse supplied to each micro bolometer is measured by two or more measuring circuits for small arrays in frame time. Furthermore, one or more known bias pulses for proofreading are supplied into frame time in a measuring circuit, Based on the measurement result of the proofreading signal which measured the proofreading signal generated as the result, and produced it as a corresponding result, the offset parameter about each small array is computed, The output signal which reduced the deficit which is not [in the picture which rectifies the signal which it was measured and was produced as a result by the calculation offset parameter relevant to it, and an array generates] desirable is generated.
