Abstract

Conventional non-convex phase retrieval algorithms struggle with local minima and false solutions, in particular in the presence of noise. These issues are overcome with a linearized phase retrieval algorithm for multi-probe nearfield measurements without global reference signal. We present measurement results to verify that this algorithm works well with noisy real-world measurement data, given a suitably designed probe array and sufficient oversampling.
