Abstract

A gas absorption spectrum measuring system, including a light source, a light source controller, a light intensity detector and a computing module is provided. The light source emits a light. The light source controller regulates a wavelength of the light. The light intensity detector detects an intensity of the light which is generated by the light source and passes through at least one target gas. The computing module includes a numerical processor and a storage unit. The storage unit stores a spectral database. The numerical processor fits an absorption spectrum of the at least one target gas and a standard spectrum in the spectral database, performs a similarity comparison operation to obtain a temperature and a pressure of the at least one target gas with a minimum residual value, and determines a species concentration of the at least one target gas according to the minimum residual value.
