Paper Abstract

A multi-reflection cell has been employed to increase the sensitivity of the detection of methane gas. However, as the requirements of the detection system need to work on a low frequency range, the influence of the 1/f noise will be considered. This paper deal with this problem by investing the signal processing methods using Fast Fourier Transform (FFT) results have been shown an improvements of about 75% in the methane gas readings.
