Abstract

A novel fiber-optic evanescent wave sensor is presented. The sensor, composed of a lead salt tunable infrared laser and a multimode uncladded silver halide infrared optic fiber, was used for rapid measurement of sulfur hexafluoride pressures at a few-percent detection limit. High-precision detection and identification of a large variety of gases are possible.
