Researchers use tightly focused laser beams to image biological samples, shape materials with microscopic precision and ...

A technique that supersizes cells to reveal minute details has gone big — really big. Using a polymer similar to those used in nappies to make them super-absorbent, scientists have expanded the volume ...

With a new microscope that's as light as a penny, researchers can now observe broad swaths of the brain in action as mice move about and interact with their environments. As a mouse explores its ...

Researchers have incorporated a swept illumination source into an open-top light-sheet microscope to enable improved optical sectioning over a larger area of view. The advance makes the technique more ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

a, An axi-symmetric binary phase filter (BPF) and image reconstruction network are jointly learned through the physics-informed neural network. The learned BPF is fabricated and inserted in a pupil ...
