Python implementation of Phase Sorting Interferometry (PSI) for estimating non-common path errors in High Contrast Imaging (HCI) instruments.
This PSI package is developed primarily for ELT/METIS, but also for VLT/ERIS.
This work is based on the initial work of Emiel Por, followed-up by the work of Matthew Willson†:
- fepsi : written by Emiel Por and modified by Matthew Kenworthy (Leiden University)
- psi : preliminary package developed by Matthew Willson† for METIS (Liège University)
The initial commit of this repository is a copy of psi.
- "Focal Plane Wavefront Sensing Using Residual Adaptive Optics Speckles" by Codona and Kenworthy (2013), ApJ, 767, 100.
Code requires the following Python package : hcipy and all its dependencies.
The ffmpeg tools are required for generating movies.
HCIPy is a Python software package written and developed by Emiel Por for performing end-to-end simulations of high contrast imaging instruments for astronomy.
