Generating multi-wavelength phase screens for atmospheric wave optics simulations using fast Fourier transforms
Milo W. Hyde, Matthew Kalensky, Mark F. Spencer
We present a method to synthesize phase screens for multi-wavelength, atmospheric wave optics simulations using fast Fourier transforms. We validate our work by comparing the theor…

Wavefront errors in two-wavelength adaptive optics systems
Milo W. Hyde, Matthew Kalensky, Mark F. Spencer
Two-wavelength adaptive optics (AO) systems sense turbulence-induced wavefront distortions using an artificial beacon or natural guidestar at one wavelength, while correcting and p…

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…
