Sensing and control of segmented mirrors with a pyramid wavefront sensor in the presence of spiders
Noah Schwartz, Jean-François Sauvage, Carlos Correia +9
The segmentation of the telescope pupil (by spiders & the segmented M4) create areas of phase isolated by the width of the spiders on the wavefront sensor (WFS), breaking the spati…
