Anisoplanatic errors in two-wavelength adaptive optics
Milo Hyde, Mark Spencer, Matt Kalensky
Two-wavelength adaptive optics (AO) systems sense wavefront errors using a beacon at one wavelength, while correcting for subsequent imaging or beam projection at another. Although…

Closed-form expressions for the centroid-tilt error due to scintillation
Milo W. Hyde, Eric W. Mitchell, Mark F. Spencer
In adaptive optics, the tracker and wavefront sensor commonly measure irradiance centroids (in their respective focal planes) to estimate the turbulence-degraded wavefront in the p…
