摘要

Optoelectronic components and subsystems such as optically controlled phased array antennas,distributed radar networks,interferometric optical fiber hydrophones,and high-speed optoelectronic chips demand high-accuracy optical time delay measurement with large measurement range and the capability for single-end and wavelength-dependent measurement.In this paper,the recent advances in the optical time delay measurement of a fiber link with high accuracy are reviewed.The general models of the typical time delay measurement technologies are established with the operational principle analyzed.The performance of these techniques is also discussed.
