摘要
To realize imaging detection of aerosol distribution, a plane detection system was proposed based on planar laser-induced fluorescence (PLIF) technology for distribution of aerosol concentration. Firstly, the single pixel detection ability of this plane detection system was analyzed theoretically. And then, taking fluorescein as the target particle, the power distribution and attenuation changes of planar laser at wavelength 450 nm were calculated. Finally, according to fluorescence signal in the wavelength range of 500~600 nm and SNR formula of the single pixel of the sCMOS camera, the influence of different system parameters on the detectable particle minimum number of single pixel and their distribution differences in the detection plane were discussed. The results show that the simulation analysis can help to understand the influence of different parameters on the performance of imaging detection of aerosol distribution, and provide an effective method and theoretical basis for plane detection of aerosol distribution. © 2023 Beijing Institute of Technology.
