Software for High Order Wavefront Sensing and Control (HOWFSC) with Coronagraphs

About this technology

Overview

The High Contrast Imaging Testbed (HCIT) Facility has been a leader in high contrast imaging research for the past two decades. The pairwise probing method for focal plane wavefront estimation and the Electric Field Conjugation (EFC) method for focal plane wavefront control developed and proven in the HCIT have been used across the world for achieving high contrast with coronagraphs. To support the first high contrast imaging instrument in space with active wavefront control, the Roman Space Telescope Coronagraph Instrument, the legacy HCIT software for pairwise probing and EFC was greatly improved with extensive unit testing and documentation. This new software package, named HOWFSC, is available in Python.
