Popis: It has been demonstrated both with computer simulation and field experiments that low order adaptive optics can improve the signal to noise ration in subsequent computer post- processing algorithms, especially when viewing an extended object. In this presentation we show open and closed loop images of a meteorological satellite taken with a low order adaptive optics instrument package mounted on the side of the Air Force's 3.5 meter telescope. The images are subsequently post-processed using speckle algorithms. It is shown that the boost in post-processing signal to noise ratio, provided by the low order adaptive optics, closely corresponds to computer simulation results.
