摘　　要：The first photon bias of photon detection results in distortion of the photon waveform,which seriously affects the accurate acquisition of target information.A rapid universal recursive correction method is proposed,which is suitable for multi-trigger and single-trigger modes of photon detection.The calculation time is 2 to 3 orders of magnitude faster than that of Xu et al.'s method.In the experiment,we have obtained good correction results for area targets and targets with varying depths.When the average number of echo photons is 0.89,the correlation distance of the correction waveform is reduced by 85%.
