Low-order wavefront control using a Zernike sensor through Lyot coronagraphs for exoplanet imaging: II. Concurrent operation with stroke minimization

R. Pourcelot, E. H. Por, M. N'Diaye +16

Wavefront sensing and control (WFSC) will play a key role in improving the stability of future large segmented space telescopes while relaxing the thermo-mechanical constraints on…

Building a GRAVITY+ Adaptive Optics Test Bench

The Gravity Plus Consortium, Florentin Millour, Philippe Berio +22

We present the testbench aimed at integrating the GRAVITY+ adaptive optics GPAO. It consists of two independent elements, one reproducing the Coud{é} focus of the telescope, includ…

Low-order wavefront control using a Zernike sensor through Lyot coronagraphs for exoplanet imaging

R. Pourcelot, M. N'Diaye, E. H. Por +19

Combining large segmented space telescopes, coronagraphy and wavefront control methods is a promising solution to produce a dark hole (DH) region in the coronagraphic image of an o…
