Simple Optical Fiber Sensor for Express and Cross-Sensitive Hydrogen Detection.

ABSTRACT: The utilization of hydrogen as an energy source is becoming more and more widespread. Since hydrogen is a highly explosive gas, its use requires the development of inexpensive and simple sensors capable of measuring hydrogen concentrations under a variety of conditions. These sensors must meet several parameters, such as small size, light weight, corrosion resistance, and remote operation capability. The ideal hydrogen sensors should also be insensitive to the presence of various interfering gases and humidity or temperature variation and be protected against potential poisoning. In this work, we present a simple optical hydrogen sensor that satisfies most of the above criteria. The sensor is based on a plasmon-active multimode optical fiber coated with Pd and PDM layers in a stepwise mann
