An optical field sensing system and an associated method are provided that
are tolerant of scintillation. The system includes a wavefront sensor
that measures gradients across a wavefront at a first resolution defined
by the subapertures of the wavefront sensor. The system also includes an
intensity sensor that measures the intensity across the wavefront at a
higher resolution. The system further includes a wavefront processor that
determines respective phases across the wavefront. In addition to the
gradients and the intensity measurements, the wavefront processor may
determine the respective phases based also upon the noise affiliated with
the measurements. In this regard, the wavefront processor may determine
the respective phases across the wavefront at least partially based upon
the gradients as adjusted by weights that are based upon the intensity
measured by the intensity sensor and are influenced by evidence of
scintillation.
