Pupil replication and hypertelescope systems for imaging telluric exoplanets in scattered light are treated. Analytic expressions for the spread functions in one and two dimensions and in the presence of various forms of error are given. Error effects considered include aperture misalignment, tilts, piston, pointing errors, and unequal beam amplitude. The performance of the two approaches is contrasted, and the analytic results are compared with simulation results. © 2007. The American Astronomical Society. All right reserved.
