Consider a scenario of imaging through atmospheric turbulence. A digital approach for processing out the turbulence from degraded images is under development. In contrast to past approaches only two short-exposure images are needed as inputs. Here we test the benefits to be gained by inserting object power spectrum information into the algorithm.
