This lecture provides an introduction to wavefront reconstruction and dynamic control in adaptive optics (AO) systems. We will explore the key principles, including the application of inverse-problem theory to wavefront reconstruction and optimal/sub-optimal control to real-time DM correction, such as feedback loops, control matrix techniques, and optimization strategies to compensate for...
This lecture provides an introduction to the design of AO systems: how to specify wavefront sensors, wavefront correctors, AO control systems, and implementation errors based on performance requirements, such as residual wavefront error and sky coverage, and observing conditions, such as atmospheric turbulence and observatory-induced disturbances. The lecture will show how residual errors can...
This lecture outlines the process of designing an AO system for VLT, beginning with top-level requirements and covering the steps up to commissioning. The development experience of the UT4 instrument ERIS will be used as an example, highlighting challenges, solutions, and lessons learned.
