摘要：

The spatial and temporal non-uniformities in infrared focal plane array (IRFPA) result a slowly varying pattern on the image thereby, degrading the resolving capabilities of thermal imaging system considerably. A method based upon the variation of the integration time and its implementation for calibrating the sensor non-uniformities is presented. The results are compared with the black body based calibration method. This approach results the same residual non-uniformities as obtained using black body method. However, this approach offers the much required field upgradability, making the system more robust giving same performance under all environmental conditions. (c) 2007 Elsevier B.V.
