摘要
针对红外焦平面阵列探测元响应具有非线性特征 ,提出了一种易于硬件电路实现的、考虑探测元响应非线性的非均匀性校正方法 .通过理论分析和仿真实验 ,结果表明该方法校正参数少 。
Aiming at the nonlinearity of photoresponse characteristic in infrared focal plane arrays, a new approach to non-uniformity correction in IRFPA was proposed, which is simple and easy to implement by hardware circuit. The theoretical analysis and comparisons of simulation results show its performance is more perfect than that of the piecewise linear algorithm and the polynomial fitting algorithm, and only a few correction factors are needed.
