Low-order wavefront control using a zernike sensor through lyot coronagraphs for exoplanet imaging – blind stabilization of an image dark hole

HIGHLIGHTS

• who: Pourcelot R. and colleagues from the Universitu00e9 Cu00f4te d`Azur, Observatoire Cu00f4te d`Azur, CNRS, Laboratoire Lagrange, Nice, France Department of Mechanical and Engineering, Princeton University, Princeton, NJ, USA have published the research work: Low-order wavefront control using a Zernike sensor through Lyot coronagraphs for exoplanet imaging - Blind stabilization of an image dark hole, in the Journal: (JOURNAL)
• what: The authors propose an active control scheme using Zernike wavefront sensor (ZWFS) to analyze light rejected by FPM control low-order aberrations and stabilize DH contrast. By controlling first 11 Zernike modes the authors . . .
