HIGHLIGHTS
- who: Chambouleyron V. and collaborators from the CNRS, CNES, LAM, France have published the research work: Focal-plane-assisted pyramid wavefront sensor: Enabling frame-by-frame optical gain tracking, in the Journal: (JOURNAL)
- what: To mitigate these effects the authors propose to use in addition to the classical pyramid sensor focal plane image combined with convolutive description of the sensor to fast track the PyWFS non-linearities the so-called optical gains (OG). The authors show that this additional focal plane imaging path only requires small fraction of the total flux while representing robust solution . . .
