Abstract

The use of prior knowledge is important for effective phase retrieval in biological imaging using coherent light. We design a new algorithm based on alternating direction method of multipliers (ADMM), where physical constraints in the imaging system are used as prior knowledge. Experimental results where we apply the method on a masked coherent diffractive imaging (CDI) system show the efficiency of our algorithm.
