2019 Spirit of Lyot Conference Report
November
8,
2019
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: Johns Hopkins University Students' Project
June
4,
2018
The demanding requirements for HiCAT drives continual innovation. The precise optics work best in a controlled, enclosed area which has to be taken into account when designing the chamber.
HiCAT: First Demonstration of a Coronagraph Dark Zone in Broadband Light with a Segmented Aperture
April
22,
2018
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
April
4,
2018
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
March
28,
2018
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.
PASTIS: Applications to Sensitivity Analysis of Segmented Telescopes
February

2018
Take a deeper look into how PASTIS is used for sensitivity analysis of segmented telescopes.
JOST: Integration of a New Camera
February
21,
2018
Out with the old, in with the new. JOST got a new camera that is brand-spanking-new!
HiCAT: Second Deformable Mirror(DM) Calibrated and Installed

Update on our second deformable mirror.
Pair-based Analytical model for Segmented Telescopes Imaging from Space (PASTIS): Introduction to the Model
February
13,
2018
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.
