Back-Propagating the Light of Field Stars to Probe Telescope Mirrors Aberrations

F. Soulez, F. Courbin, M. Unser

Proceedings of the SPIE Astronomical Telescopes + Instrumentation Conference on Advances in Optical and Mechanical Technologies for Telescopes and Instrumentation II (SPIE-ATI'16), Edinburgh, United Kingdom, June 26-July 1, 2016, vol. 9912, pp. 991277-1/991277-7.



We propose a wavefront-based method to estimate the PSF over the whole field of view. This method estimate the aberrations of all the mirrors of the telescope using only field stars. In this proof of concept paper, we described the method and present some qualitative results.
