Compensation of phase noise impairments in distributed acoustic sensors based on optical pulse compression time-domain reflectometry
We introduce a method to compensate for the deleterious effects of the phase noise of the laser source on long-range distributed acoustic sensors (DAS) that implement optical pulse compression (OPC). Pulse compression can ... -
Long-range traffic monitoring based on pulse-compression distributed acoustic sensing and advanced vehicle tracking and classification algorithm
We introduce a novel long-range traffic monitoring system for vehicle detection, tracking, and classification based on fiber-optic distributed acoustic sensing (DAS). High resolution and long range are provided by the use ... -
Phase noise effects on phase-sensitive OTDR sensors using optical pulse compression
We introduce a detailed theoretical, numerical, and experimental study of the effects of laser's phase noise on the performance of phase-sensitive optical time-domain reflectometry (-OTDR) sensors that use optical pulse ... -
Two-wavelength phase-sensitive OTDR sensor using perfect periodic correlation codes for measurement range enhancement, noise reduction and fading compensation
We demonstrate a two-wavelength differential-phase-measuring OTDR sensor that uses perfect periodic correlation phase codes to enhance the measurement performance. The two-wavelength technique extends the measurement range ...
