Paper Abstract

A Lorentzian shaped point spread function (PSF) for adaptive optics is demonstrated. In some cases, a Lorentz atop an Airy pattern is a better description of the PSF. If the object can also be described with an analytic function, then Parametric Blind Deconvolution can be applied as a self referencing method to extract information about both the object and PSF simultaneously. The technique is used to derive the triaxial shape and rotational pole of the asteroid Vesta from observations made on the night of October 18, 1997, marking the first time the high order loop was closed for science with the Starfire Optical Range 's 3.5m telescope.
