Proc. SPIE 13097, Adaptive Optics Systems IX, 1309744 (29 August 2024)
In the near-infrared wavelength regime, atmospheric turbulence fluctuates at a scale of a few milliseconds, and its precise control requires the use of extreme adaptive optics (XAO) systems equipped with fast and sensitive detectors operating at kHz
