摘      要：Accurate values of masked detector signal(MDS)is the key to the correction capability of wavefront sensorless(WFSless)model-based adaptive optics(AO)***,imaging detectors always carry different kinds of noises in real applications,which make MDS deviate from theoretical *** errors of MDS suffered from the noise were analyzed through theory and ***,considering the method of threshold is usually used to mitigate the noise,we also discussed the influence of threshold on *** showed that the simulation is consistent with the theory and there exists an optimal threshold to make the error minimum for different noise.A fi tting formula,which can accurately calculate optimal thresholds,was proposed based on the simulated *** results can provide a plausible method and theoretical basis to mitigate imaging noise of detectors in real applications.
