Myopic deconvolution method for adaptive optics images of stellar fields.

FUSCO T., VERAN J.-P., CONAN J.-M. and MUGNIER L.M.

Abstract (from CDS):

The atmospheric turbulence severely limits the angular resolution of ground based telescopes. When using Adaptive Optics compensation, the wavefront sensor data permit the estimation of the residual PSF. Yet, this estimation is imperfect. A ``myopic'' deconvolution method which takes into account this estimation and its associated noise is presented. This technique is applied to adaptive optics corrected images of star fields. It is based on a stochastic approach which uses the available information about the object and about the PSF. This technique allows the simultaneous restoration of star parameters (position with sub-pixel precision and accurate photometry) and of the PSF. The algorithm is successfully applied both to simulated and to experimental data.
