Abstract

We want to improve imaging through the turbulent atmosphere. At the entrance pupil the object spectrum is color dependent, but the projection of the atmosphere is barely so. This situation is reversed in the focal plane, so the optimum approach measures the atmosphere with a broad band of light in the pupil such that the object is sensed as little as possible. Then the object information is extracted from the focal plane (F.P.) measures. Nevertheless, simultaneous measures with two first-rate area detectors are expensive, so we here emphasize what can be done with one F.P. area detector.
