Rapid Scanning Measurement of Inhomogeneity in Calorimetric Optical Power Detectors
摘要
Abstract
The inhomogeneity of response is a key parameter for a calorimetric optical detector.Due to the thermal equilibrium process,calorimetric detectors have relative long response time.In order to improve the measurement efficiency of the inhomogeneity of the detectors,a two-dimensional scanning measurement system is constructed,and the scanning experiments are carried out with different scanning interval time,the inhomogeneity characteristics obtained under different scanning interval times are statistically evaluated.Methods based on comparison of the image similarity of the inhomogeneity and the calculation of the variance of the two-dimensional raw data are applied.The results show that when the scanning interval time is no less than 45%of the full response time,the deviation of the rapid scanning is no more than 0.2%compare to the full scanning.With further reduction of the scanning interval time,the difference between the rapid measurement and the full response measurement is gradually increased,results in 20%inequality while the scanning interval time reduced to 20%of the full response time.The feasibility of rapid scanning measurement to measure inhomogeneity under incomplete detector response is experimentally demonstrated,which significantly improved the speed of inhomogeneity measurement on the basis of a reliable measurement results.关键词
