Wavelet-Forward Family Enabling Stitching-Free Full-Field Fourier Ptychographic Microscopy (Laser Photonics Rev. 19(3)/2025)

Abstract

Wavelet-Transform Models of FPM

In article number 2401183, Shuhe Zhang, Jinhua Zhou, and co-workers present a family of forward models based on wavelet transform for Fourier ptychographic microscopy and its variations. The wavelet forward model extracts a multi-scale feature pyramid of the sample data with topologically diverse wavelets, forming the data fidelity during the optimization. The wavelet forward model achieves stitching-free, high-resolution, and highly robust Fourier ptychographic synthetic aperture even under challenging conditions.
