The point spread function (PSF) describes the response of a focused optical imaging system to a point source or point object. A more general term for the PSF is the system's impulse response; the PSF is the impulse response or impulse response function (IRF) of a focused optical imaging system. The PSF in … See more By virtue of the linearity property of optical non-coherent imaging systems, i.e., Image(Object1 + Object2) = Image(Object1) + Image(Object2) the image of an object in a microscope or telescope as a non … See more Microscopy In microscopy, experimental determination of PSF requires sub-resolution (point-like) radiating sources. Quantum dots and fluorescent beads are usually considered for this purpose. Theoretical models as described above, on … See more The point spread function may be independent of position in the object plane, in which case it is called shift invariant. In addition, if there is no distortion in the … See more The diffraction theory of point spread functions was first studied by Airy in the nineteenth century.
