Abstract
An optical fibre gas sensor using a pressure-modulation resonant-acoustic reference cell is employed to pressure modulate technique is demonstrated. A the absorption of a gas in the near infra-red. The system exhibits good selectivity, low response to contaminant gases, and a noise-limited sensitivity equivalent to 50ppm by volume for methane sensing.
