-In this paper, we study the temperature change of a μ-bolometer focal plane array with a capacitive transimpedance amplifier bias cancellation circuit. Thermal analysis is essential to understand the performance of a μ -bolometer focal plane array, and to improve the temperature stability of a focal plane array characteristics. In this study, the thermal analyses of a μ-bolometer and its two reference detectors are carried out as a function of time. The analyses are done with the 30㎛ pitch 320x240 focal plane array operating of 60 Hz frame rate and having a columnwise readout. From the results, the temperature increase of a μ-bolometer in FPA by an incident IR is estimated as 0.689 ℃, while the temperature increase by a pulsed bias as 7.1 ℃, which is about 10 times larger than by IR. The temperature increase of a reference detector by a train of bias pulses may be increased much higher than that of an active μ -bolometer. The suppression of temperature increase in a reference bolometer can be done by increasing the thermal conductivity of the reference bolometer, in which the selection of thermal conductivity also determines the range of CTIA output voltage.

The radiance coming from the interior of an uncooled infrared camera has significant effect on the quality of an infrared image. The classical two-point-correction (TPC) method fails to remove this effect where no TPC data is collected. To overcome this deficit, this paper presents a three-phase scheme. First, from a set of samples and through least squares fitting, how the TPC datum varies with the interior temperature of the camera is determined. On this basis, all the necessary TPC data are calculated. Finally, the collected infrared image is corrected with the TPC method. Theoretical analysis and experimental results show that, for a proper interior temperature of the camera, the scheme can remove the effect effectively.
