Demostración de un sensor de gas metano basado en un ...

Hollow-core photonic bandgap fibres (HC-PBFs) have been recently demonstrated as a powerful technology in the field of gas sensing. The long interaction path lengths available with these fibers are advantageous for the detection of weakly absorbing gases such as methane. However, long path lengths also yield to very high insertion times of the gas into the fiber. In this paper, a novel ...
