This training session is part of the 2024 Sagan Summer Workshop on Advances in Direct Imaging: From Young Jupiters to Habitable Earths. For complete workshop information see: https://nexsci.caltech.edu/workshop/2024/
Optical modeling plays an integral part in designing and analyzing the performance of high-contrast imaging systems. This hands-on session will teach you the basics of how such diffraction calculations are performed, for both space- and ground-based telescopes, and will provide valuable insights into the behavior of light within complex optical systems. We will use HCIPy for all simulations in this session.
During this session, you will learn:
How to compute point-spread-functions for telescope pupils.
How different coronagraphs modify the light in pupil and focal planes.
How to visually identify common alignment issues in coronagraphic images.
How aberrations impact the coronagraphic image and how speckles interact.
How to compute throughput for off-axis sources.
Methods for speeding up computation of dynamic aberrations.
