摘要
Abstract
Nonlinearity of the sweep circuit of streak camera distorts the time and intensity information of the streak image. In order to make the streak image closer to the actual object and to improve the measuring precision, this paper presents a correction algorithm based on image processing. It fits the sweep time curve based on the nominal sweep time to obtain the sweep time of each channel, and chooses the mean value of the sweep time as a criterion. According to the numerical relation between the criterion and the sweep time of each channel, the position and intensity of each pixel are corrected. The result indicates that this algorithm can reduce the nonlinearity to less than 2% from the original 8%.关键词
