Konijnenberg, A.P. (author), Coene, W.M.J.M. (author), Urbach, Paul (author)A noise-robust extension of iterative phase retrieval algorithms that does not need to assume a noise model is proposed. It works by adapting the intensity constraints using the reconstructed object. Using a proof-of-principle ptychographic experiment with visible light and a spatial light modulator to create an object, the proposed method is...journal article 2018

Konijnenberg, A.P. (author), Coene, W.M.J.M. (author), Urbach, Paul (author)We report on a novel non-iterative phase retrieval method with which the complex-valued transmission function of an object can be retrieved with a non-iterative computation, with a limited number of intensity measurements. The measurements are taken in either real space or Fourier space, and for each measurement the phase in its dual space is...journal article 2016
