Highest resolution imaging in astronomy is achieved by interferometry, connecting telescopes over increasingly longer distances and at successively shorter wavelengths. Here, we present the first ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to ...

A laser beam is shone onto a variable rectangular aperture. The size of the hole determines the type of diffraction produces on the screen. Very small apertures produce Fraunhofer diffraction, and ...

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 ...

Fluorescence microscopy techniques are powerful tools for probing very small signals and revealing three-dimensional (3D) structural and functional properties of biological samples with high ...
