Abstract:
In this paper, we demonstrate the acetylehe (C2H2) sensor with high sensitivity using a hollow-core photonic bandgap fiber (HC-PCF). Experiments for measuring C2H2 concentrations in gas mixture are performed. Using a 2 m-long HC-PCF as gas cell, the spectrum of acetylene at n1+n3 band has been measured, and the P11-branch has been selected for the purpose of sensing. A minimum detectivity of 143 parts per million by volume (ppmv) for the system configuration is estimated. 更多还原
