Punktspreadfunktionen
Punktspreadfunktionen, which translates to "point spread function" in German, is a concept in the field of optics and physics. It refers to the effect of a physical system, such as an optical system, on the position and shape of point sources of light. The point spread function (PSF) describes how light from a point source is distributed in the image plane of an optical system, taking into account the effects of aberrations, diffraction, and other optical phenomena.
In essence, the PSF is a mathematical representation of how an optical system convolves a point source
The concept of the point spread function has significant implications for the field of optics, as it
