Phase-tilting interferometry for optical testing is proposed to retrieve the phase from interferograms with random phase tilts. The Radon transform is used to extract the tilted phase plane, and the phase distribution is retrieved by the least squares method. The proposed method has been applied to simulated and experimental interferograms, obtaining satisfactory results. The proposed method has high accuracy and good robustness, and it can be used for interferometric measurements in environmental vibrations. Additionally, it can be used for interferometers without a phase shifter to achieve high-precision analysis.
提出了用于光学测试的相倾斜干涉测量法，以从具有随机相倾斜的干涉图中恢复相位。利用 Radon 变换提取倾斜相位平面，并通过最小二乘法恢复相位分布。该方法已应用于模拟和实验干涉图，得到了令人满意的结果。该方法具有高精度和良好的鲁棒性，可用于环境振动中的干涉测量。此外，它还可用于没有相移器的干涉仪，以实现高精度分析。
