The shapes of light sources such as electron beams can be reconstructed by inverse Fourier transformation of the complex degree of spatial coherency, which can be measured using Young's interferometer. The application of the phase-retrieval algorithm to reduce phase measurement errors in the complex degree of spatial coherency is numerically studied using an electron beam with an asymmetric distribution. This application is demonstrated with experimental data measured at the diagnostic beamline at the Pohang Accelerator Laboratory.
光源的形状，如电子束，可以通过对空间相干性的复程度进行傅里叶逆变换来重建，而这可以使用杨氏干涉仪来测量。使用相位恢复算法来减少空间相干性的复程度中的相位测量误差的应用，通过使用具有非对称分布的电子束进行了数值研究。该应用是通过在浦项加速器实验室的诊断束线上测量的实验数据进行演示的。
