Routines for wavefront propagation in IDL, Matlab, and Python
PROPER is a library of routines for the propagation of wavefronts through an optical system using Fourier-based methods. It was developed at the Jet Propulsion Laboratory for modeling stellar coronagraphs, but it can be applied to other optical systems were diffraction propagation is of concern. It is currently available for IDL (Interactive Data Language), Matlab and Python (2.7 & 3.x). It includes routines for generating complex apertures and obscurations and aberrations (Zernike & PSD-defined). It includes a model of a deformable mirror for wavefront control. The routines perform near and far field propagation with automatic selection of propagators. All Python users are urged to download v3.0b, which has some major bug fixes. The latest Python version is v3.0b released on 6 Mar 2018. IDL and Matlab versions are v3.0a from 22 Jan 2018.
The aim of this project is to facilitate the development of open source software for the acceptance testing of commonly used PET (positron emission tomography) systems in accordance with published NEMA standards.
This is a set of spectral models for use in the astronomical X-ray spectral modeling program XSPEC. The models calculate X-ray emission line Doppler profiles from the winds of OB stars.
