Spatially Variant PSF Modeling and Image Deblurring

É. Thiébaut, L. Denis, F. Soulez, R. Mourya

Proceedings of the SPIE Astronomical Telescopes + Instrumentation Conference on Adaptive Optics Systems V (SPIE-ATI'16), Edinburgh, United Kingdom, June 26-July 1, 2016, vol. 9909, pp. 99097N-1/99097N-10.



Most current imaging instruments have a spatially variant point spread function (PSF). An optimal exploitation of these instruments requires to account for this non-stationarity. We review existing models of spatially variant PSF with an emphasis on those which are not only accurate but also fast because getting rid of non-stationary blur can only be done by iterative methods.
