Abstract

Предложена система обнаружения распределенного газа, которая содержит волокна с твердотельной сердцевиной, волокна с полой сердцевиной и запрашивающее устройство. Волокна с твердотельной сердцевиной выполнены с возможностью приема света одной или нескольких длин волн от источника света. Волокна с полой сердцевиной расположены в разных местоположениях. Каждое волокно с полой сердцевиной оптически соединено с другим соответствующим одним волокном с твердотельной сердцевиной и выполнено с возможностью приема по меньшей мере части света, прошедшего через указанное соответствующее волокно с твердотельной сердцевиной. Запрашивающее устройство выполнено с возможностью приема по меньшей мере части света, распространяющегося через волокна с твердотельной сердцевиной и волокна с полой сердцевиной. Запрашивающее устройство выполнено с возможностью идентификации местоположения наличия представляющего интерес газа путем изучения поглощения по меньшей мере одной из длин волн света по меньшей мере в одном волокне с полой сердцевиной.
