Issue Date: | 2016 | Volume: | Adaptive Optics Systems V | Editors: | Marchetti, Enrico; Close, Laird M.; Véran, Jean-Pierre | Series: | PROCEEDINGS OF SPIE | Number: | 9909 | First Page: | 99096K | Abstract: | In this paper we report on the laboratory experiment we settled in the Shanghai Astronomical Observatory (SHAO) to investigate the pyramid wave-front sensor (WFS) ability to measure the differential piston on a sparse aperture. The ultimate goal is to verify the ability of the pyramid WFS work in close loop to perform the phasing of the primary mirrors of a sparse Fizeau imaging telescope. In the experiment we installed on the optical bench we performed various test checking the ability to flat the wave-front using a deformable mirror and to measure the signal of the differential piston on a two pupils setup. These steps represent the background from which we start to perform full close loop operation on multiple apertures. These steps were also useful to characterize the achromatic double pyramids (double prisms) manufactured in the SHAO optical workshop. | Conference Name: | Adaptive Optics Systems V | Conference Place: | Edinburgh, UK | Conference Date: | 26 June-1 July, 2016 | URI: | http://hdl.handle.net/20.500.12386/25910 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9909/99096K/Sparse-aperture-differential-piston-measurements-using-the-pyramid-wave-front/10.1117/12.2232374.full https://arxiv.org/abs/1608.00390 |
