Abstract

Abstract

The measurement of beam size is important for optimizing system parameters and ensuring stable operation of synchrotron radiation light sources. An interferometric method was adopted to measure the vertical size of beam section at Hefei Light Source. Based on the theory of Cittert-Zernike, the size of beam section can be calculated according to the double-slit interferogram contrast. The interferometric system consists of interference imaging system and image processing system. The results of the five experiments conducted agree well with the theoretical value, verifying the effectiveness of the interferometric method.
