Abstract: In this work, gas sensors using laser-reduced graphene oxide (LrGO) as sensitive layer have been fabricated and studied. The laser-synthetized material was structurally and electrically ...

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 ...
