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 ...

Quarterly of Applied Mathematics, Vol. 7, No. 1 (APRIL, 1949), pp. 45-64 (20 pages) The problem of diffraction and scattering of a normally incident plane wave of sound by an infinite plane grating ...

THE peculiar character of the photographs of an opening to the sky in the dark Cyclopean gallery at Tiryns, to which Mr. W. J. Stillman calls attention (NATURE, vol. xxiv. p. 260), finds an obvious ...

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 ...

A sharp-edged aperture is a promising solution for eliminating side lobes from superoscillatory waves. Optical superoscillation refers to a wave packet that can oscillate locally in a frequency ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...
