Abstract

Relative wavefront phasing errors between the beam trains that make up a synthetic aperture beam expander can be estimated from the far-field interference patterns produced by samples of wavefronts propagated through adjacent beam trains. Wavefront sensor and estimation algorithms are presented, and the effect of noise and higher-order errors on performance is described.
