DMD-addressing based ptychographic phase microscopy

This paper presents DMD-addressing based ptychographic phase microscopy (DA-PPM) and phase/fluorescence dual-modality imaging in DA-PPM. Compared with conventional ptychographic approaches, the imaging speed of DA-PPM is significantly enhanced by DMD based illumination selection, and is further enhanced by parallel illumination, i.e., lighting up parallelly multiple sub-areas in one shot. Furthermore, two-folds spatial resolution enhancement can be achieved in DA-PPM by incorporating structured illumination generated by DMD. Last but not least, phase/fluorescence dual-modality imaging will be performed in DA-PPM, providing for the same sample complementary information, including structural and functional information.
