Optical ammonia sensors based on Hollow core fiber and photoacoustic spectroscopy

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review


Gas sensors are of great interest in detection and monitoring of air pollution. We report on the sensing of ammonia gas using two optical modalities. We demonstrate an all-fiber based hollow core ammonia gas sensing and a photoacoustic based sensing of ammonium solution. Both systems demonstrate fast response time, high repeatability and cost effectiveness
