2019 Spirit of Lyot Conference Report

In late October, a subset of the Makidon lab group set out to Tokyo to attend the “Spirit of Lyot” conference. Happening only every 3-5 years, this conference brings together everybody working in high-contrast imaging, sharing their work in the spirit of Bernard Lyot, the inventor of the coronagraph.

HiCAT: First Demonstration of a Coronagraph Dark Zone in Broadband Light with a Segmented Aperture

Recently on HiCAT, we obtained a very first dark hole with a broadband light source, combining a segmented aperture, a coronagraph (Apodized Pupil Lyot Coronagraph or APLC), and wavefront control (the Speckle Nulling method, now running on demand in any configuration).

HiCAT: First Results with the COFFEE Wavefront Sensor

Last week, Jean-François Sauvage (from the Office National d’Etudes et de Recherches Aérospatiales and the Laboratoire d’Astrophysique de Marseille) has been invited by STScI to come to the Makidon Lab to implement and test the COFFEE wavefront sensor on HiCAT data.

JOST: Installation of the HiCAT Python Package

For a couple of years now, our group had been doing really good work in developing first-class coronagraph technology and wavefront sensing techniques for segmented apertures. During this process, one of the focus points of the work is to create a concise python package which controls the HiCAT testbed and its environment and which would eventually be ready to be freely shared for implementation on other high-contrast testbeds.

Pair-based Analytical model for Segmented Telescopes Imaging from Space (PASTIS): Introduction to the Model

The PASTIS model provides a fast way to compute the contrast in the dark hole generated by a coronagraph, and affected by local errors on the segments. In this post, we introduce our very first results using this model and compare them with the outputs of a traditional end-to-end simulation.
