Reconstruction methods for the phase-shifted Zernike wavefront sensor

Vincent Chambouleyron, Mahawa Cissé, Maïssa Salama +8

The Zernike wavefront sensor (ZWFS) stands out as one of the most sensitive optical systems for measuring the phase of an incoming wavefront, reaching photon efficiencies close to…

Towards understanding interactions between the AO system and segment co-phasing with the vector-Zernike wavefront sensor on Keck

Maïssa Salama, Charlotte Guthery, Vincent Chambouleyron +14

We extend our previous demonstration of the first on-sky primary mirror segment closed-loop control on Keck using a vector-Zernike wavefront sensor (vZWFS), which improved the Stre…

Keck Primary Mirror Closed-Loop Segment Control using a Vector-Zernike Wavefront Sensor

Maissa Salama, Charlotte Guthery, Vincent Chambouleyron +17

We present the first on-sky segmented primary mirror closed-loop piston control using a Zernike wavefront sensor (ZWFS) installed on the Keck II telescope. Segment co-phasing error…
