| Abstract: | An instrument based on the principle of optical attenuation was developed for the real-time measurement of black carbon aerosol in atmosphere. The working principle, hardware design and software design of the instrument are introduced. A single chip processor is used to control the collecting, processing and displaying of signals. The instrument can detect the concentration of black carbon aerosol in atmosphere rapidly. Comparative experiments show that the design of the instrument is reasonable and the instrument is able to meet the requirement of on-line measurement. |
