WebThe PSF is the Fourier transform of the OTF, which means that it represents the amplitude distribution resulting from OTF-like pulse. Its intensity is the PSF squared, i.e. the 4th power of the ASF, with the ring structure nearly vanishing (as it is to expect, with the OTF-like pulse having in general similar shape to the Gaussian pulse (i.e ... WebHere, we develop a method to fit an experimentally derived point spread function (PSF) model to the interference 4Pi-PSF. As the interference phase is not fixed with respect to the shape of the PSF, we decoupled the phase term in the model from the 3D position of the PSF. ...

WebJan 24, 2016 · The image of a point source is known as the point spread function (PSF) of the microscope. In signal processing, it's known as a two dimensional impulse response. The equation that relates the image of the isotropic point source to the pupil function P ( k x, k y) is PSF A ( x, y) = ∬ P ( k x, k y) exp [ − j ( k x x + k y y)] d x d y WebThe PSF is a valid measure for the quality of an optical system as it reveals how points are blurred in the image. Because the PSF is always normalized (i.e., the integral over its entire span is equal to 1), it is easy to compare …
