Abstract: (1262 Views)
Monitoring the security of sensitive environments is of particular importance due to the reduction of damage during natural and unnatural events. Last generation sensors do not meet the existing requirements due to various weaknesses such as short measurement distance, high cost, failure to determine the location of the event, etc., and the need for extensive monitoring systems. On the other hand, distributed fiber optic sensors have attracted attention due to outstanding advantages such as high speed, immunity to electromagnetic interference, accurate location of the event, long range and low maintenance costs. In this paper, a 2 km long distributed fiber optic sensor system is designed and implemented based on the reflection Rayleigh scatter phase analysis method to monitor human passage in the fiber range. Finally, two distinct targets, including a human and a 80 Hz vibrating motor, were identified from a distance of 1200 and 1000 m from the beginning of the fiber with an SNR of 39 and 27 dB, respectively.
