摘要: 束流截面尺寸测量对优化系统参数、确保光源运行至关重要。采用干涉法测量合肥同步辐射光源束流截面垂直方向的尺寸。基于Cittert-Zernike 定理，利用双缝干涉条纹的对比度得出相干度和束流截面尺寸。测量系统由干涉成像与图像处理系统组成。进行了5组试验，试验结果证明了干涉法测量合肥同步辐射束流截面尺寸的可行性。

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.
