Abstract
A new non-destructive readout scheme for IR array detectors, which allows image sharpening by on chip tracking has been tested with the ESO IR array camera IRAC2. This camera is equipped with a large format NICMOS3 256*256 MCT array detector. The effect of the readout algorithm is equivalent to a first order wavefront correction of images degraded by atmospheric seeing. Correction is performed in real time for long on chip detector integrations. Results obtained at a 2.2 m telescope on the pre main sequence binary star S CrA, the Circinus galaxy and the cluster NGC3603 will be presented. Possible applications of this method at large 8 m telescopes will be discussed.
