Abstract

This article describes a dynamic signal processing program that utilizes 2-D photon counter data and forms the Fourier transform of an image while phase-tracking the individual space-frequency components. Both phase and amplitude spectra are well behaved. Inverse Fourier transforms from the mean phases and mean amplitudes illustrate the imaging performance of the procedure using observations of a double star with a small telescope and verify the legitimacy of the tracking at fairly low light levels. A subset of the procedure is also suggested as an interferometric star tracker having a greater sensitivity bandwidth product than that available from previous techniques.
