Title:
LIGHT PULSE TRAIN SYNCHRONIZER, LIGHT PULSE TRAIN SYNCHRONIZING METHOD, ILLUMINATION APPARATUS, DETECTION APPARATUS, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2016/125458
Kind Code:
A1
Abstract:
A light pulse train synchronizer configured to synchronize a first light pulse train 21 including light pulses produced periodically at a first period and a second light pulse train 22 including light pulses produced periodically at a second period includes a light detector 5, 6 configured to output a first signal corresponding to at least one of a light intensity of the first light pulse train and a light intensity of the second light pulse train, a light detector 10 configured to output a second signal corresponding to a timing difference, and a control circuit 11 configured to output a control signal for adjusting at least one of the first period and the second period so that the second signal is equal to a target value obtained from the first signal.
