I use simulated adaptive optics data to demonstrate a noise removal technique exploiting prior knowledge of the angular support of the object. Using both detector-noise limited and speckle-noise limited data, I show that this method can result in significant increases in the sensitivity of speckle interferometry to faint companions under demanding observing conditions.
