红外焦平面探测器非线性度拟合参数分析
|
摘要
从理论上分析了光子型红外焦平面探测器各输入输出参数之间的线性关系。对典型320×256长波红外焦平面探测器在不同拟合参数下的非线性度进行了测试,并与理论计算结果进行了比较。结果表明采用输出信号电压与波段光子数或黑体波段辐照功率进行拟合,可以使理论上带来的非线性度减至最小,能够更为准确地评价红外焦平面探测器的非线性度。
The linear relationship between the input and output parameters of photon infrared focal plane array(FPA) detectors is analyzed theoretically. For a typical 320×256 long-wave infrared FPA detector, the nonlinearities of various fitted parameters were measured and compared with theoretically computed values.The results show that the fitting of the output signal voltage and band photon number or blackbody band irradiation power minimizes the nonlinearity in theory. This makes the evaluation of the nonlinearity of the infrared FPA detector more accurate.
