Design and performance of a mechanical strain optical sensor using a multimode fiber locally stressed by a periodical micrometric perturbation

SPIE Proceedings, 2010
We present a new kind of intrinsic intensity modulation optical fiber sensor. The sensitive effect is obtained by a mechanical perturbation of the fiber at the micrometric scale. The fiber diameter and the refractive indices are locally modified. The principle of this sensor is a losses modulation in this perturbed zone of the fiber due to different ...

Periodic variation of stress field in the Koyna–Warna reservoir triggered seismic zone inferred from focal mechanism studies

Tectonophysics, 2016
Abstract The Koyna–Warna region in western India is globally recognized as the premier site of reservoir triggered seismicity (RTS) associated with the Koyna and Warna reservoirs. The region is characterized by continuous seismic activity observed since several decades, including the world's largest triggered earthquake of M6.3 which occurred in ...
