Abstract

A new technique is described for high resolution imaging through the atmospheric turbulence. As in speckle interferometry, short exposure images are recorded, but in addition the associated wavefronts are measured by a Hartmann-Shack wavefront sensor. The knowledge of the wavefront allows to calculate the instantaneous point spread function. An estimate of the object can be calculated from the correlation of image and point spread function. An experimental set up is described with first laboratory results. It shows the capabilities of the method.
