Abstract: To take full advantage of lab-on-fiber technologies for gas sensing, we propose a reflective Fabry-Perot interferometer (FPI) CO2 gas sensor composed of the functional material ...

Abstract: A compact-type nondispersive infrared (NDIR) carbon dioxide (CO2) sensor featuring a novel optical sensing cell (OSC) is designed and developed using ray-guided multi-reflector (RGMR) and ...
