Soft Realtime Control of an Exoplanet Imaging Instrument

To photograph nearby systems of exoplanets, astronomical instruments require the use of advanced real time control techniques to counteract the shimmering turbulence of the Earth’s atmosphere. We will show how we are using Julia in our lab to record and process images from high speed cameras, send control signals hundreds of times per second, and present a rich graphical interface with live telemetry. We will discuss technical considerations on using Julia in this domain.
