Abstract

A method for imaging extended objects using adaptive optics technique is proposed. The wavefront distortion is corrected by using the Fourier transforms of two image intensities obtained with and without a Gaussian amplitude filter at the entrance pupil plane of the imaging system. A one dimensional computer simulation is presented, which shows the effectiveness of the method.
