Aperture-Scanning Fourier Ptychographic Encoding with Phase Modulation

Phase modulation is first introduced into aperture-scanning Four/er ptychography. A series of images are acquired with an aperture scanning the Fourier plane of an optical system with a phase modulator.

Summary:Phase modulation is first introduced into aperture-scanning Four/er ptychography. A series of images are acquired with an aperture scanning the Fourier plane of an optical system with a phase modulator. Then the reported algorithm synthesizes the captured images in the frequency domain to recover a high-resolution complex object wavefront. The leading results are considerably improved in robustness against the noises and shift errors, with a much faster convergence speed compared with the conventional scheme without phase modulation.
