High contrast imaging using coronagraphy is one of the main avenues to enable
the search for life on extrasolar Earth analogs. The HiCAT testbed aims to
demonstrate coronagraphy and wavefront control for segmented on-axis space
telescopes as envisioned for a future large UV optical IR mission (LUVOIR). Our
software infrastructure enables 24/7 automated operation of high-contrast
imaging experiments while monitoring for safe operating parameters, along with
graceful shutdown processes for unsafe conditions or unexpected errors. The
infrastructure also includes a calibration suite that can run nightly to catch
regressions and track optical performance changes over time, and a testbed
simulator to support software development and testing, as well as optical
modeling necessary for high-contrast algorithms. This paper presents a design
and implementation of testbed control software to leverage continuous
integration whether the testbed is available or not.
