| Summary:
LLNL has recently setup a High Contrast Testbed (HCT) for AO and exoplanet
imaging technology development. We present the various HCT technologies
currently under development, including (1) a Wynne corrector, (2)
multi-wavefront sensor (WFS) single conjugate AO (SCAO) control. We present HCT
testing results of a first Wynne corrector prototype with a self-coherent
camera. We present updates on development efforts to design and apply multi-WFS
SCAO control to our HCT setup. We also present ongoing HCT deformable mirror
and WFS upgrades. Lastly, we present developments for REDWOODS, a project to
deploy many of these technologies on-sky on a sub-bench of the Shane AO system
at Lick Observatory.
