On a universal solution to the transport-of-intensity equation
Jialin Zhang, Qian Chen, Jiasong Sun +2
Transport-of-intensity equation (TIE) is one of the most well-known approaches for phase retrieval and quantitative phase imaging. It directly recovers the quantitative phase distr…
Learning-based real-time method to looking through scattering medium beyond the memory effect
Enlai Guo, Shuo Zhu, Yan Sun +2
Strong scattering medium brings great difficulties to optical imaging, which is also a problem in medical imaging and many other fields. Optical memory effect makes it possible to…
Resolution analysis in a lens-free on-chip digital holographic microscope
Jialin Zhang, Jiasong Sun, Qian Chen +1
Lens-free on-chip digital holographic microscopy (LFOCDHM) is a modern imaging technique whereby the sample is placed directly onto or very close to the digital sensor, and illumin…
Dynamic 3-D measurement based on fringe-to-fringe transformation using deep learning
Haotian Yu, Xiaoyu Chen, Zhao Zhang +3
Fringe projection profilometry (FPP) has become increasingly important in dynamic 3-D shape measurement. In FPP, it is necessary to retrieve the phase of the measured object before…
Wide-field high-resolution 3D microscopy with Fourier ptychographic diffraction tomography
Chao Zuo, Jiasong Sun, Jiaji Li +2
We report a computational 3D microscopy technique, termed Fourier ptychographic diffraction tomography (FPDT), that iteratively stitches together numerous variably illuminated, low…
High-speed in vitro intensity diffraction tomography
Jiaji Li, Alex Matlock, Yunzhe Li +3
We demonstrate a label-free, scan-free {\it intensity} diffraction tomography technique utilizing annular illumination (aIDT) to rapidly characterize large-volume 3D refractive ind…
Temporal phase unwrapping using deep learning
Wei Yin, Qian Chen, Shijie Feng +5
The multi-frequency temporal phase unwrapping (MF-TPU) method, as a classical phase unwrapping algorithm for fringe projection profilometry (FPP), is capable of eliminating the pha…
Optimal illumination scheme for isotropic quantitative differential phase contrast microscopy
Yao Fan, Jiasong Sun, Qian Chen +3
Differential phase contrast microscopy (DPC) provides high-resolution quantitative phase distribution of thin transparent samples under multi-axis asymmetric illuminations. Typical…
