Method for measuring a time interval and means for applying this method

摘要

A moving object (E) uses a micro laser to emit pulses of period (Tm) which are received by photodiodes (Dn). The photodiode signals are digitized (CANn), integrated (ITn) and used by a sequencer (SQ) and generator of impulses (G1) to start a counter (Cn) at the end of the integration period. The counter is stopped at the reception of the next microlaser pulse and the time used to determine the distance of the moving object after receiver synchronisation correction
