Original Abstract

A sensing system utilizing the standard optical fiber as a distributed sensor for detection and localization of the mechanical vibrations is presented. Vibrations can be caused by various external factors like moving people, cars, trains, and other objects producing mechanical vibrations that are sensed by a fiber. In our laboratory we have designed a sensing system based on phase -OTDR (phase sensitive Optical Time Domain Reflectometry) using extremely narrow laser and EDFAs.

Senzorický systém umožňující použití standardního optického vlákna jako distribuovaného senzoru pro detekci a lokalizaci mechanických vibrací je zde prezentován. Vibrace mohou být způsobeny několika různými faktory, jako jsou chodící lidé, jedoucí automobily, vlaky a další objekty způsobující mechanické vibrace, které mohou být snímány optickými vlákny. Vnaší laboratoři jsme navrhli tento systém založený na principu fázového OTDR (fázově citlivého optického reflektometru) využívající extrémně úzkopásmového laseru a EDFA zesilovačů.
