Integrated Module Of Distributed Fiber Optic Vibration Detection System
DVS integrated hardware module, based on which you can more quickly implement your own distributed vibration measurement system, you only need to match the DAQ, and then focus on the implementation of software!!
DvS integrated module integrates narrow linewidth fiber laser, AOM acousto-optic regulator, pulse EDFA, annularizer, Raman amplifier, high signal-to-noise ratio photoelectric conversion module, only need to be equipped with a high-speed data DAQ can form a set of DVS distributed vibration measurement system.
