Abstract A method suitable for recording radial-shearing holograms is proposed. By inserting a phase-shifting Theon-ladder zone plate at the Fourier plane of Kepler telescope, perfectly matched interferogram can be obtained with high contrast and good quality. Good image quality should meet not only theoretical resolution, but also good interference contrast. Interference pattern generated by the multicopies of the object will achieve the best contrast, which could significantly improve the quality of reconstructed image. The interferograms of multicopies were achieved with the help of the Kepler system, and the reconstruction with the same theoretical resolution was provided. An equivalent experiment on USAF1951 resolution test target verifies the effectiveness of our proposed method. As a kind of common-path setup, the proposed radial-shearing method not only takes full advantage of the detector screen but also provides the high signal-to-noise ratio hologram.

完美匹配的径向剪切全息与相移 Theon-ladder 波带片

摘要 提出了一种适合记录径向剪切全息图的方法。通过在开普勒望远镜的傅里叶平面上插入一个相移的Theon-ladder波带片，可以获得具有高对比度和高质量的完美匹配的干涉图。好的图像质量不仅要满足理论分辨率，还要满足良好的干涉对比度。物体的多副本产生的干涉图案将达到最佳对比度，这可以显着提高重建图像的质量。在开普勒系统的帮助下获得了多拷贝的干涉图，并提供了具有相同理论分辨率的重建。在 USAF1951 分辨率测试目标上的等效实验验证了我们提出的方法的有效性。作为一种公共路径设置，
