A novel technique for measuring the instantaneous arrival times of a long series of consecutive photoevents effective at shorter intrapulse intervals up to 10 ns with an accuracy of better than 1 ns has been developed and tested experimentally and by simulations. It is based on linear processing without dead time effects of detector pulses by excitation of a resonant system, analog/digital sampling, deconvolution, and calculation of single pulse centers and electric charges. The maximum number of processed photoevents exceeds103at108pulse rate. In an accumulation regime the method can be used for temporal profiling of the number of photocounts with very high resolutions up to 0.1 ns. This method covers the intermediate range of photon rates, where the well known techniques are ineffective. It can be applied for high order photon statistics, in lidar sensing, time-resolved spectroscopy, as well as in typical electronic measurements of instantaneous frequencies, periods etc. ©1998 American Institute of Physics.
