High order dark wavefront sensing simulations
Roberto Ragazzoni, Carmelo Arcidiacono, Jacopo Farinato +8
Dark wavefront sensing takes shape following quantum mechanics concepts in which one is able to "see" an object in one path of a two-arm interferometer using an as low as desired a…
Dark tip-tilt sensing
Carmelo Arcidiacono, Roberto Ragazzoni, Valentina Viotto +6
Dark wavefront sensing in its simplest and more crude form is a quad-cell with a round spot of dark ink acting as occulting disk at the center. This sensor exhibits fainter limitin…
Sparse aperture differential piston measurements using the pyramid wave-front sensor
Carmelo Arcidiacono, Xinyang Chen, Zhaojun Yan +7
In this paper we report on the laboratory experiment we settled in the Shanghai Astronomical Observatory (SHAO) to investigate the pyramid wavefront sensor (WFS) ability to measure…
The numerical simulation tool for the MAORY multiconjugate adaptive optics system
Carmelo Arcidiacono, Laura Schreiber, Giovanni Bregoli +14
The Multiconjugate Adaptive Optics RelaY (MAORY) is and Adaptive Optics module to be mounted on the ESO European-Extremely Large Telescope (E-ELT). It is a hybrid Natural and Laser…
