The Terrestrial Planet Finder Coronagraph (TPF-C) is a future NASA mission to search for earth-like planets around nearby stars. The tremendous sensitivity needed primarily rests on the stability of the wavefront over several hours. One way this wavefront can change is by lateral motion of the beam (beam walk) across the mirror surfaces due to mispointing of the entire telescope or of individual mirrors. A deformable mirror (DM) corrects the exit pupil wavefront initially to extremely high quality, but beam walk changes the wavefront presented to that DM, so that its setting is no longer ideal. This paper present a simple method to estimate the power spectral density of these wavefront changes.
