WebApr 13, 2024 · Fourier Optics. The Generalized Pupil Function is significant because, with an on-axis unit impulse of light and a few other assumptions typically valid in photography, the magnitude squared of the Fourier Transform of such an Exit Pupil is the intensity Point Spread Function projected onto the Gaussian point by the relative aberrated lens. 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 The diffraction theory of point spread functions was first studied by Airy in the nineteenth century. He developed an expression for the point spread function amplitude and intensity of a perfect instrument, free of aberrations (the so-called See more • Circle of confusion, for the closely related topic in general photography. • Airy disc • Encircled energy 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 system, the image plane coordinates are linearly related to the object plane … 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

WebJun 9, 2024 · The answer is, “Yes!”. Mathematically, the blurring of the PSF with the actual arrangement of fluorophores in the specimen is called a convolution of the specimen with the PSF: Specimen \ast PSF = Image S pecimen ∗ P S F = I mage. It’s no accident that the symbol for convolution ( \ast ∗) looks like a multiplication since the two ... WebDec 4, 2024 · Eric Bezzam. 26 Followers. PhD student at EPFL.
