Laboratory Demonstration of Optimal Identification and Control of Tip-Tilt Systems
Aditya R. Sengupta, Benjamin L. Gerard, Daren Dillon +3
We present the results of testing optimal linear-quadratic-Gaussian (LQG) control for tip and tilt Zernike wavefront modes on the SEAL (Santa cruz Extreme AO Lab) testbed. The cont…
SCALES for Keck: Optical Design
Renate Kupke, R. Deno Stelter, Amirul Hasan +9
SCALES is a high-contrast, infrared coronagraphic imager and integral field spectrograph (IFS) to be deployed behind the W.M. Keck Observatory adaptive optics system. A reflective…
Various Wavefront Sensing and Control Developments on the Santa Cruz Extreme AO Laboratory (SEAL) Testbed
Benjamin L. Gerard, Javier Perez-Soto, Vincent Chambouleyron +7
Ground-based high contrast imaging (HCI) and extreme adaptive optics (AO) technologies have advanced to the point of enabling direct detections of gas-giant exoplanets orbiting bey…
Laboratory Demonstration of Real-Time Focal Plane Wavefront Control of Residual Atmospheric Speckles
Benjamin L. Gerard, Daren Dillon, Sylvain Cetre +1
Current and future high contrast imaging instruments aim to detect exoplanets at closer orbital separations, lower masses, and/or older ages than their predecessors. However, conti…
