Abstract

A novel scheme of gas concentration detection based on a frequency modulation technique is introduced in this paper, which resolves the problems of centric wavelength drift and variations of modulation amplitude by using an ASE source, FBG and a specific mechanical vibration device. A wavelength Scanning optical source for gas detection can be easily achieved.
