Deep convolutional neural network-based lensless quantitative phase retrieval

Abstract

<p>In this paper, we employ a deep convolutional neural network for the solution of the phase retrieval problem in a lensless optical system from a single observation. We utilize U-net-like structured DCNN to reconstruct phase from the amplitude images at the sensor plane, and after applying computational backpropagation, the complex objects’ amplitude is reconstructed at the object plane. Results are demonstrated by simulation experiments.</p>
