Mathematical Processing of Pulses for Improving the Timing Characteristics of the Correlation Counter

The systematic error in measuring the duration of flashes by the correlation counter that was developed by the authors earlier on the basis of a digital oscilloscope and a computer has been reduced by 1–2 ns by mathematical processing of input pulses and by correction of their recording times. The variance in the measured duration and delay of flashes does not change when the correction is applied. The technique has been tested on model flashes, and the time of sonoluminescence flashes has been clarified. The counter can be used to measure other fast events, e.g., in nuclear physics.
