Embodiment Construction

[0028] The Fourier transform infrared spectrometer uses the principle of Michelson interferometer to make the 632.8nm laser generated by the helium-neon laser produce interference phenomenon and act as a collimated light source. The infrared broadband light source and the laser are in an optical path system. After the infrared light source is interfered, the interference data is collected by A / D. After the data is Fourier transformed, the spectral data of the infrared light can be obtained, and then the concentration of the gas to be measured can be analyzed. .

[0029] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0030] According to an embodiment of the present invention, a Fourier transform infrared spectrometer is provided, such as figure 1 As show...
