Quasi-distributed long-gauge fiber optic sensor system
This paper presents a quasi-distributed, long-gauge, sensor system for measurement optical path length variation. This system can be directly applied to long gauge strain and/or temperature sensing. The proposed sensor system is comprised of sensing…

Multimode all-fiber quasi-distributed refractometer sensor array and cross-talk mitigation
The analysis and design of a quasi-distributed multimode fiber refractometer array is presented. The main challenge in the design of a practical quasi-distributed sensor array proved to be in mitigation of otherwise pronounced cross-talk effects…

In-line short cavity Fabry-Perot strain sensor for quasi distributed measurement utilizing standard OTDR
This paper presents an in-line, short cavity Fabry-Perot fiber optic strain sensor. A short air cavity inside a single-mode fiber is created by the fusion splicing of appropriately micro machined fiber tips. A precise tuning…
