Non-common path aberration compensation and a dark hole loop with a pyramid adaptive optics system: Application to SAXO+
C. Goulas, R. Galicher, F. Vidal +16
In ground-based high-contrast instruments, non-common path aberrations (NCPAs) limit detection performance, as they are unseen by the adaptive optics (AO) wavefront sensor but impa…

Increasing the raw contrast of VLT/SPHERE with dark hole techniques III. Broadband reference differential imaging of HR\,4796 using a four-quadrant phase mask
Raphael Galicher, Axel Potier, Johan Mazoyer +3
Imaging exoplanetary systems is essential to characterizing exoplanetary systems and to studying planet-disk interactions to understand planet formation. Such imaging in the visibl…
