Abstract
In harsh and hazardous environments, the presence of elevated levels of hydrogen gas is an indicator of chemical and/or radiological activity. The present hydrogen-sensing optical fiber provides rapid and reliable hydrogen detection and quantification, irrespective of temperature fluctuations. The hydrogen-sensing optical fiber does not exhibit significant irreversible hydrogen-induced attenuation losses after exposure to a hydrogen-rich atmosphere.
