In this paper, we proposed a random phase retrieval approach based on two differential interferograms and VU factorization. Firstly, three interferograms with arbitrary phase shifts are subtracted, and then two differential interferograms are obtained. On this basis, the phase related to the matrix is solved via VU factorization and the measured phase is obtained. Compared with the commonly used high-accuracy phase-shifting algorithms, this method does not require long-time iteration and approximate conditions, so there is no requirement for the shape and number of fringes of the interferogram. More importantly, it is an extremely stable and high-accuracy phase-shifting algorithm, which has great advantages for practical applications. Experiments and simulation analysis show that the proposed method is a random phase retrieval approach with good anti-noise and strong applicability.
