Amplitude-type self-healing spiral phase contrast imaging. (a) Self-healing edge detection experimental setup. (b) Comparison of the sizes of the objects and obstacles. (c, d) Letter images and corresponding self-healing spiral phase contrast images with obstacle diameters of 0 μm, 100 μm, 200 μm or 300 μm. Scale bar: 400 μm. (e, f) The respective normalized intensity distributions of the results in (c, d) for obstacle diameters of 0 μm, 100 μm, 200 μm and 300 μm.
