The Telescope Diagnosed Its Optics From Ordinary Stars
A revised WaveDiff recovered wide-field wavefront error to about three percent using only noisy in-focus observations.
Summary
A revised WaveDiff recovered wide-field wavefront error to about three percent using only noisy in-focus observations.
WaveDiff combines a differentiable optical model with learned wavefront features to infer telescope aberrations from stellar images. A projection step linking its parametric and learned components reduced simulated wavefront-recovery error from about 30 percent to about three percent while slightly improving pixel-space modeling. The result was demonstrated on noisy, undersampled observations in simulation and still needs instrument-specific validation.
Why it matters
