Quasi-Dome: A Self-Calibrated High-NA LED Illuminator for Fourier Ptychography

Not Accessible

Your library or personal account may give you access


We demonstrate an inexpensive programmable color LED array illuminator with 0.98 numerical aperture (NA), coupled with an auto-calibration procedure, to enable a simple and efficient setup for high-angle Fourier Ptychography in a commercial microscope.
