Architecture For Distributed Acoustic Sensing Interrogation For Sensor Deployment

Abstract: a distributed acoustic system (das) that may include two or more lasers that each transmit a continuous wave (cw) light, a pulser disposed after the two the two or more lasers and optically connected to each of the two or more lasers to receive the cw light from each of the two or more lasers and form a light pulse, and an optical amplifier, wherein the pulser is optically connected to the optical amplifier to receive the light pulse from the pulser as an input. the das may further include a splitter optically connected to the optical amplifier to optically split the light pulse into two or more light pulses for each output of the splitter a circulator optically connected to each output of the splitter, and a sensor fiber attached to each of the circulators as an output for each circulator.
