Abstract: A multimode fiber (MMF) speckle pattern is proposed to demodulate a distributed Bragg reflector (DBR) fiber laser sensor. DBR light source emits a highly coherent laser, and the speckle ...

Abstract: As some physical parameter measurements (e.g. vibration) require a high-speed FBG demodulation system, a high-speed scanning module as the core part of this system is investigated. In this ...
