Description

technical field [0001] The invention relates to an infrared signal detection device used in a roadside airway air quality monitoring system, belonging to the field of applied optics. Background technique [0002] At present, the common infrared signal detection devices have short optical path or single-wavelength detection, and the detection sensitivity is low. The multi-wavelength detection device generally installs the filter wheel and the infrared detector separately, and the structural stability is poor, which is not conducive to weak signal detection. Contents of the invention [0003] The purpose of the present invention is: to provide an infrared signal detection device used in the air quality monitoring system of the side respiratory tract, which can perform multi-filter fast multi-wavelength signal detection through high-speed rotating filter wheel, and has high structural stability, In order to solve the problems of low detection sensitivity of existing single-wa...
