Nonuniform optical sampling signal reconstruction algorithm

optical pulse generated by mode-locked lasers has lower time jitter than electronics, which is the main advantage of optical sampling. However, by using multiplexer to further increase the repetition rate of optical pulse will cause nonuniformity in amplitude and time delay. Here we discuss the effect brought by this kind of static deviation, and propose the reconstruction algorithm in Nth-order nonuniform optical sampling. Experiment results show that it can effectively build the original signal.
