Fundamental diffraction physics says that a larger aperture improves both resolution and penetration. However, aperture size has historically been limited by system complexity and unknown benefit in ...

The pattern may be bigger, and red light is likely less sensitive to imperfections in the grating. Some of the special edition banknotes in circulation don't have the maple leaf diffraction grating.

When laser energy is deposited in a target material, numerous complex processes take place at length and time scales that are ...

When a laser beam is incident on many small objects such as lycopodium powder, the resulting diffraction pattern is similar to the diffraction pattern of a small circular aperture (Airy's disk pattern ...

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 ...

The waves always 'spread' to some extent into the area beyond the gap. This is diffraction - the spreading out of waves when they go through a gap, or past the edge of a barrier. The extent of the ...

The interactions between light and nitroaromatic hydrocarbon molecules have important implications for chemical processes in ...

A joint research team led by Yuuki Kubo and Shiji Tsuneyuki of the University of Tokyo has developed a new computational ...
