A black carbon aerosol concentration detection system by light attenuation

On the basis of studying an atmospheric black carbon aerosol concentration detection system, a black carbon aerosol concentration detection method based on optical attenuation method is proposed. First, this method and its inversion are analyzed theoretically. Then, hardware design of optical detection circuit and software design of aerosol concentration inversion algorithm are described in detail. Finally, the detection results are displayed and analyzed by management software on the computer. The experimental results indicate that this proposed detection system can arrive at the anticipated goal.
