Wavefront corrections over large fields of view via beam cone tomography

Imaging objects in scattering media requires the correction of complex wave distortions. Adaptive optics and wavefront shaping can correct these distortions, but aberrations are rarely isoplanatic and vary spatially over the field of view. We propose a tomographic approach to reconstruct the local refractive index distribution of a scatterer, allowing the calculation of aberration maps for larger fields of view. The approach is guided by wavefront measurements at test points around the target area. We demonstrate the ability of our tomographic approach to provide spatial aberration maps through numerical simulations and proof-of-concept experiments.
