We report the implementation of a parallel microscopy system (96 Eyes) that is capable of simultaneous imaging of all wells on a 96-well plate. The optical system consists of 96 microscopy units, where each unit is made out of a four element objectiv

Memory-efficient, Global Phase-retrieval of Fourier Ptychography with Alternating Direction Method

Autor: Changhuei Yang, Yujia Huang, Antony C. S. Chan, An Pan

Publikováno v: Imaging and Applied Optics 2019 (COSI, IS, MATH, pcAOP).

We propose to use alternate direction method of multipliers (ADMM), to improve computational robustness of Fourier ptychographic microscopy (FPM). This method is highly parallel so it can be run efficiently on GPU or distributed CPUs.

Based on image encoding in a serial-temporal format, optical time-stretch imaging entails a stringent requirement of state-of-the- art fast data acquisition unit in order to preserve high image resolution at an ultrahigh frame rate --- hampering the

Based on the interferometric or holographic approaches, recent QPM techniques provide quantitative-phase information, e.g cell volume, dry mass and optical scattering properties for label-free cellular physical phenotyping. These approaches generally

Pixel super-resolution in optical time-stretch microscopy using acousto-optic deflector

Autor: Antony C. S. Chan, Edmund Y. Lam, Kevin K. Tsia

Publikováno v: Optics in the Life Sciences.

We present experimental demonstration of pixel super-resolution time-stretch imaging by high-speed agile-beam-steering with the use of synchronized acousto-optic deflector – enabling high-resolution imaging rate of 1MHz whereas relaxing the stringe
