Abstract

In the process of the study on power density distribution of infrared high power laser, it is convenient to acquire laser power density through processing the laser image gradation by computer.The image is obtained via the method of translation slit.The distortion induced by nonuniform motion of the slit in the process of laser power density measurement and its correctiuon is discussed in the paper.
