Phase inversion method based on focal length fixed Fresnel zone plate

The invention provides a phase inversion method based on a focal length fixed Fresnel zone plate. Part of focal plane and de-focal plane information of wavefront can be collected at the same time at the same position in the far field, only one frame of image is needed, the method based on the Fresne...
