Dear all,
I have a dataset obtained from a wavefront sensor that provides me with the values of the first 36 Zernike's Polynomials for many research subjects. I would like to derive both the point spread function (PSF) and modulation transfer function (MTF) from these data, similar to what is shown here. The PSF is especially important.
Is there any set of tools for MATLAB that will make this feasible? I am not an expert in optics.
Sincerely, Jim

To operate the instrument, read the manual: If you play a bit with the boxes of the link you include as 'here', one at a time, start with #1:1 and the rest 0, then #1:0 #2:1 rest zero and so on, you realize that #1 #2 #3 ... are the indices the indexes of Zernike equations as listed in http://fp.optics.arizona.edu/jcwyant/Zernikes/ZernikeEquations.htm PSF and MTF are just 3D plots, the term 'Irradiance' shows up, but you just have to solve each equation reading the numeral #I on the left of the table for [ro theta_x and theta_y]. Mind the gap the previous link showing the equations names theta, both theta_x and theta_y, but the far right column helps tell. Copied the table that shows x and y, as theta_x and theta_y below these lines, Courtesy of ZernikePolynomialsForTheWeb.nbJames C. Wyant, 20035.
Hope it helps
John
