DIGITAL OPTICAL SIGNAL TRANSMISSION IN A SEISMIC ARRAY

摘要

The invention describes a sensor array with digital signals transmitted over
an optical fiber for seismic exploration systems. The seismic system includes
a transducer for providing digital optical data signals and an optical
interrogator for collecting the digital data. The transducer provides data
from seismic sensors to the optical interrogator by acting on an optical
carrier transmitted along the optical fiber. The system is designed to utilize
known electromechanical seismic sensors with fiber optic telemetry.
