红外辐射测量系统的快速宽动态非均匀性校正算法
Rapid wide dynamic non-uniformity correction algorithm for infrared radiation measurement system
摘要
Abstract
In this paper,a rapid and wide dynamic non-uniformity correction algorithm is proposed for the re-quirement of continuous change of integration time in infrared radiation measurement system.The algorithm considers the impact of integration time effect and stray radiation of the optical system.The experimental verification was conducted by employing cooled mid-wave infrared radiation characteristic measurement sys-tem with a 25 mm aperture.The correction efficiency of the classical algorithm and the proposed algorithm are compared.The results indicate that the proposed algorithm is 3.4 times more efficient than the traditional non-uniformity correction algorithm.On the above basis,we evaluate the effect of the two algorithms on the image correction using residual non-uniformity.Multiple integration times(0.6 ms,3 ms and 3.5 ms)are used to simulate the continuous change of integration.The results indicate that the residual non-uniformity of the proposed algorithm is consistent and the image has been effectively corrected.关键词
