Abstract
In a device for measuring the time interval between first and second optical pulses, the time interval between the first optical pulse and a first one of the train of reference optical clock pulses which is closest to the first optical pulse, and the time interval between the second optical pulse and a second one of the train of reference optical clock pulses which is closest to the second optical pulse are measured, and the time interval between the first and second optical pulses is calculated according to the time intervals thus measured and the time interval between the first and second reference optical clock pulses.
