Abstract

A photon-camera star tracker was developed for use in a ground-based optical stellar interferometer. A major advantage gained by using a photon camera as the light detecting element is that it allows the received image to be cross-correlated with any desired spatial function. A theoretical analysis is presented to show that proper selection of a cross-correlation function can result in improved tracking performance. In addition, the optical, electronic, and software design of the star tracker is discussed.
