Focal plane phase retrieval using deep convolutional neural networks: A study on the feasibility of phase retrieval in free space optical communications from a single out of focus intensity measurement using a deep convolutional neural network

Adaptive optics are widely used to correct the wavefront distortion imposed by atmospheric turbulence. Focal plane phase retrieval from intensity measurements has advantages due to the ease of implementation, potential broader application, less computations, low cost, high system bandwidth, simplified hardware and less calibration. To cope with...
