摘要

Abstract: This paper presents the measurement of the exhaust plume field of a solid rocket with a moire interferometer. The principle of the moire interferometer is presented. The moire interferograms of the plume were processed with computer digital image processing techniques. It was found that the grey distribution of the moire interferograms has a sharp valley, and from the analysis this paper presented a method to thin and trace a deformed moire fringe on one step. This paper presents the result of the quantitative measurement.!5
