An old simulation I did that shows this effect is shown below; light that is incident vertically from below on an aperture in a opaque (blue) screen spreads in all directions: The natural question to ask: how does diffraction through a large number of holes result in different colors of ...
Arbitrary-phase-modulated array illuminator (APM-AIL) based on Talbot effect means that arbitrary-phase-modulated phase plate may generate the specific intensity distribution at the specific fractional Talbot distance. The previous understanding is that only the specific phase modulated Talbot illuminator ...
