For the understanding of the mechanisms of particle acceleration in pulsars, it is necessary to determine the high energy cutoff of the pulsed emission. In order to derive upper limits (or detections) on the pulsed emission in the TeV energy range using Cherenkov telescopes, typically data taken over periods of months or even years are superimp osed. It is therefore necessary to use a time capture system and analysis to ols which provide a base for pulsar phase analysis which is stable over a time-scale of years. We have built a device consisting of a photomultiplier tube with a fast current digitization system and components of the timing system of the H.E.S.S. experiment, which allows to measure pulsed optical emission making use of the large mirror area of Cherenkov telescopes. The system was installed into the first H.E.S.S. Cherenkov telescope in January 2003, where data was taken over 8 nights on the Crab and Vela pulsars. Optical pulsation from the Crab pulsar could be measured with observation times as short as a second. This system can therefore be used to determine the pulsar phase and to monitor the short term and long term stability of the timing system of the H.E.S.S. experiment.
