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.© (1990) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
