Belt conveyor speed detection based on fiber-optic Sagnac interferometer vibration sensor

Yaru Hou,
Pingjuan Niu,
Jia Shi
et al.

Abstract: With their long transportation distance and high productivity, belt conveyors are characterized as the main equipment for bulk material transportation in coal mines and other key industries. However, its speed detection method has always been an engineering challenge under harsh working conditions. In this work, the elastic-optical effect of the polarization-maintaining fiber is used to design a fiber ring laser vibration sensing system based on a fiber-optic Sagnac interferometer vibration sensor and its pack… Show more
