Path: Imaging/PSFUtils
% Finds the output of each imager pixel through numerical integration of PSF.
The default plot output colors the pixels as a function of height. A built in
2D Gaussian function is available for demos or as a reasonable approximation
to a real point spread function.
funPSF must be of the form:
funPSF(x,y,d)
x and y are arrays passed by integral2. They are two dimensional. Your
function must return the same size array. funPSF gets passed the
centroids and intensities of the point spread functions through the
data structure d as d.rPSF and d.iPSF. You can attach any other
data you want to d.funData as shown above.
Type ImagerPSF for a demo using RHSGaussianPSF. The demo is for a 70 by 60
pixel imaging chip.
