WebOTF = psf2otf (PSF) computes the fast Fourier transform (FFT) of the point-spread function ( PSF) array and creates the optical transfer function array, OTF, that is not influenced by the PSF off-centering. OTF = psf2otf (PSF,sz) specifies the size, sz, of the optical transfer … WebApr 18, 2012 · The simplest way to think about it is that the Optical Transfer Function is the Fourier transform of the point-spreading function (PSF). Usually PSF is a filter (convolution kernel) that describes how a single pin-hole type light source would get smeared into an actual image via some device. The OTF is just the amplitude/phase representation of ...
