What is point spread function in microscopy?
Introduction. The ideal point spread function (PSF) is the three-dimensional diffraction pattern of light emitted from an infinitely small point source in the specimen and transmitted to the image plane through a high numerical aperture (NA) objective.
What is PSF in astronomy?
The Point Spread Function (PSF) is the response of an optical instrument to an impulse. It characterizes how much the observed light distribution has been distorted by the instrument. Therefore knowing the PSF is fundamental in astronomy for morphometric and photometric measurements.
What is PSF engineering?
The PSF is defined as the square of the modulus of the amplitude point spread function, h(v), which has the form(1)h(v)=[2J1(v)v] From: Handbook of Image and Video Processing (Second Edition), 2005.
