Scientific paper

Curvature sensing, unlike some other wavefront sensing techniques, treats the boundary and interior of the aperture of interest in fundamentally different ways. This leads to complications for highly segmented telescopes (100 or more segments), as a significant fraction of points on the wavefront are simultaneously in the interior of the overall aperture and near a segment boundary. Although this effect may make it difficult to implement curvature sensing for adaptive optics on such telescopes, it may conversely be exploited for primary mirror segment alignment. We present numerical simulations which show that curvature methods should be an effective method for segment tip/tilt alignment on highly segmented mirrors.
