Fourier ptychographic microscopy at telecommunication wavelengths using a femtosecond laser

[摘要] We report the implementation of the Fourier Ptychographic Microscopy (FPM) technique, a phase retrieval technique, at telecommunication wavelengths using a low-coherence ultrafast pulsed laser source. High quality images, near speckle-free, were obtained with the proposed approach. We demonstrate that FPM can also be used to image periodic features through a silicon wafer. (C) 2017 Elsevier B.V.
