Abstract
The present invention provides a laser gas detection system, which comprises: a diode laser for emitting laser beam; a fiber optic coupler for separating the beam emitted by the diode laser into the first beam and the second beam; a first spectrometer located at the rear of the detecting area; a pair of first and second collimating lens configured at the two opposite ends of the detecting area, in which the first collimating lens is used to collimate the first beam through the detecting area for being focused by the second collimating lens to enter the first spectrometer; a first light sensor, for receiving the signal from the first spectrometer; a second spectrometer for receiving the second beam; a second light sensor for receiving the signal from the second spectrometer; a light filter configured between the second spectrometer and the second light sensor for monitoring the wavelength variance scope of the diode laser; and a data processing device for receiving the signal from the first light sensor and the second light sensor, comparing the light energy difference, and also measuring the mixed gas temperature and densities of multiple gases in the detecting area.
