Simulation tool for "Influence of wave aberrations on MTF measurements modelled by the pupil function"

The provided simulation tool enables the immediate replication of the results presented in "Influence of wave aberrations on MTF measurements modelled by the pupil function."
The software contains four different models to simulate the influence of wavefront aberrations in a rectangular aperture modelled by the complex pupil function on the resulting point spread function (PSF) and modulation transfer function (MTF).
The different methods include:
-Analytical solution of the Fraunhofer integral for a rectangular aperture with no wavefront aberration (Reference case for comparison)
-Numerical superposition of elementary waves from the aperture plane employing wavefront propagation and Huygens's principle
-Numerical solution of the Fraunhofer integral in the focal plane of a lens
-Fourier-optical determination of the far field diffraction pattern of the aperture in the focal plane of a lens
For more informations about the different methods, the reader is referred to the open acces article "Influence of wave aberrations on MTF measurements modelled by the pupil function," which is accessible in the archive of the 124-th DGAO in 2023 under number B44. (https://www.dgao-proceedings.de)
