Abstract

Un sensor que comprende una fibra óptica que incluye una rejilla de Bragg y una camisa de inducción de deformación longitudinal (LSI) para inducir deformación longitudinal en la fibra óptica como una función de una carga transversal, es decir, presión o fuerza. Cuando la camisa de LSI induce deformación en la fibra óptica, la rejilla de fibra se deforma, cambiando de este modo el carácter de la luz reflejada desde la rejilla. Los cambios en carácter de la luz reflejada pueden medirse utilizando instrumentación óptica adecuada. Las características físicas y adicionales que pueden medirse/detectarse utilizando un sensor basado en camisa de LSI incluyen contenido/presencia de humedad, contenido/presencia de químicos, y temperatura. Un sensor de detección de carga transversal puede incluir estructuras de aplicación de carga transversal que comprenden la camisa de LSI bajo carga transversal, provocando que la camisa se alargue de forma controlable y de este modo induce la deformación longitudinal en la fibra óptica. Las camisas de LSI de químicos y humedad pueden comprender materiales que se abultan en la presencia del químico o la humedad.
