Review:
Point Spread Function (psf)
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
The Point Spread Function (PSF) describes how a point source of light or other signals is represented in an imaging system. It characterizes the response of the system to a point source, effectively illustrating the system’s resolution and optical performance. PSF is fundamental in fields like astronomy, microscopy, and imaging sciences, aiding in image analysis, deconvolution, and system calibration.
