Abstract: Methods and systems for correcting environmental distortion are disclosed. An example method can comprise receiving a first plurality of signals sampled in space at a first time and determining a first plurality of correction factors based on the first plurality of signals. The first plurality of correction factors can be configured to correct environmental distortion in the first plurality of signals. The first plurality of signals can be corrected by applying the first plurality of correction factors to the first plurality of signals thereby generating a corrected first plurality of signals. The corrected first plurality of signals can be provided. The method can be repeated for one or more additional pluralities of signals sampled in space at times subsequent to the first time with corresponding additional pluralities of correction factors. Each additional plurality of correction factors can be unique to a corresponding plurality of signals.
