Temporally averaged speckle noise in wavefront sensors for beam projection in weak turbulence Open
Adaptive optics (AO) compensation for imaging or coherent illumination of a remote object relies on accurate sensing of atmospheric aberrations. When a coherent beacon is projected onto the object to enable wavefront sensing, the reflected…

Resolving phase ambiguities in the calibration of redundant interferometric arrays: implications for array design Open
We provide new results enabling robust interferometric image reconstruction in the presence of unknown aperture piston variation via the technique of redundant spacing calibration (RSC). The RSC technique uses redundant measurements of the…
