Abstract:
This paper introduces a fast and efficient method to characterize a Time to Digital Converter (TDC) transfer function using Poisson process events. We propose a correction method appropriate for ASIC as well as discrete or FPGA TDCs, to be implemented on a post process unit located after the Time to Digital Converter. We then apply the presented method to a case study that demonstrates the efficiency of the correction by measuring the fluorescence lifetime of a test fluorophore by time-correlated single photon counting (TCSPC) with and without correction. The results show a much nicer signal and better fitting with a 3-fold improvement of the fluorescence lifetime accuracy.
