Optical Point Spread Function generator (with aberrations) Point Spread Function Generator in real space (without using fourier transform) the algorithm employs the generation of plane waves from the pupil plane To ensure performance, instead of sampling all points in the pupil plane a random subset of point sources is selected
PSF of an image - MATLAB Answers - MATLAB Central - MathWorks The PSF is the 'blur' that is created by your optical system when you input a point source If you don't know what the blur created by a single dot looks like, how can you restore the original image from a whole picture?
