Adaptive optics has become a valuable tool for correcting minor
optical aberrations in applications such as astronomy and microscopy.
However, due to the limited resolution of both the wavefront sensing and
the wavefront correction hardware, it has so far not been feasible to
use adaptive optics for correcting large-scale waveform deformations
that occur naturally in regular photography and other imaging
In this work, we demonstrate an adaptive optics system for
regular cameras. We achieve a significant improvement in focus for large
wavefront distortions by improving upon a recently developed high
resolution coded wavefront sensor, and combining it with a spatial phase
modulator to create a megapixel adaptive optics system with
unprecedented capability to sense and correct large distortions.
