Abstract

Fourier Ptychographic Microscopy (FPM) probes biological samples from multiple directions and provides amplitude and quantitative phase-contrast imaging in label-free modality with large space-bandwidth product. FPM is suitable to analyze tissues in hospitals and analysis labs by unskilled users. Whenever the FPM setup is misaligned, phase artifacts can prevent a correct retrieval of the sample complex amplitude. Here we show a blind method, named Multi-Look FPM, which eliminates the unwanted artifacts and allows non-expert users skipping the recalibration process. Multi-Look FPM is proved effective in the case of neural tissue slides, cell layers, and marine microalgae with complex inner structures.
