% Compute the Airy disk for defocused light. This routine uses integral to numerically integrate the distribution. Type AirDefocused for a demo. It shows several different defocus settings and also shows the Airy point spread function. Since version 11. -------------------------------------------------------------------------- Form: AiryDefocused( z, r, lambda, a, R ) -------------------------------------------------------------------------- ------ Inputs ------ z (1,1) Distance of wave plane (mm) r (1,:) Points in plane (mm) lambda (1,1) Wavelength (nm) a (1,1) Aperture (mm) R (1,1) Distance from aperture to Gaussian image plane (mm) ------- Outputs ------- p (1,1) Output -------------------------------------------------------------------------- Reference: Virendra N.
