Ammonia Detection by use of Near-Infrared Diode-Laser-Based Overtone Spectroscopy

Ammonia Detection by use of Near-Infrared Diode-Laser-Based Overtone Spectroscopy

We describe a portable diode-laser-based sensor for NH(3) detection using vibrational overtone absorption spectroscopy at 1.53 mum. Use of fiber-coupled optical elements makes such a trace gas sensor rugged and easy to align. On-line data acquisition and processing requiring
