Abstract

In-time optical wireless sensing Ammonia (NH3) using a broadband light source is proposed. By selecting a broadband light source, the emission spectrum partially overlaps with the absorption spectrum with gas under test. In our example, a C+L band light source operating in the wavelength range of 1535 nm to 1605 nm is used. The induced loss of the sensitivity by NH3 concentration is 0.0016 mW/ppm at 1531.13 nm..
