Abstract

Post Detection Turbulence Compensation has been proposed as a technique to obtain diffraction limited imaging through the atmosphere. The technique consists of two simultaneous measurements, one made at a point conjugate to the pupil plane of an optical system and one at it's focal plane. The optical transfer function of the atmosphere is constructed from the pupil plane measurement. This is then deconvolved from the focal plane image. The result is an image with resolution at or near the diffraction limit of the imaging system. The process is highly non-linear and as a result the quality of the restored images is difficult to estimate analytically. In an attempt to understand the characteristics of this process we have developed computer models to simulate speckle holography image compensation. This paper will show results of computer simulations showing reconstructed image quality versus light levels.
