Removal algorithm for crosstalk in dual-beam point-diffraction interferometry based on a four-beam interference model

Year: 2026

Type: article

Abstract: We introduce what we believe to be a novel crosstalk-removal algorithm to eliminate phase errors in dual-beam point-diffraction interferometry. The method establishes a generalized four-beam interference error model. By using Fourier-carrier least-squares fitting and an iterative optimization based on micro-perturbation, crosstalk-induced error can be effectively eliminated. To the best of our knowledge, no relevant study on mitigating such four-beam interference errors has been previously reported.
