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. Infrared broadband light source and laser are in an optical path system. After the infrared light source is interfered, the data after the interference is collected through A / D, and the data is transformed by Fourier to obtain the spectral data of infrared light, which can then analyze the concentration of the gas to be measured. .

[0029] In order to make the object, technical solution and advantages of the present invention clearer, 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 kind of Fourier transform infrared spectrometer is provided, such as figure 1 As shown, it includes: a ...
