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 among the individual sensors in Read More …

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 of the cavity length is Read More …
