摘要： The present invention discloses a multi-channel aerosol scattering absorption measuring instrument, comprising a light path device, a detection device and a gas path device. The light path device supplies three different wavelengths of laser entering the detection device in sequence; the detection device is provided with photoelectric detectors at multiple angles for measurement, so as to reduce the measurement error of aerosol scattering coefficient; the gas path device comprises a sample loading unit, a calibration unit and a sample discharging unit; and a light source from the light path device and a gas flow from the gas path device enter the photoacoustic cavity of the detection device respectively and are detected by a control unit. The aerosol scattering absorption measuring instrument of the present invention is characterized by multi-channel, multi-angular, full-scale and direct measurement of scattering phase function and absorption coefficient of aerosol particles, combines the function of synchronously acquiring the optical parameters of an aerosol (such as scattering coefficient, extinction coefficient, visibility, transmittance, single scattering albedo, etc.), and achieves the integrated on-line detection of different optical parameters of an aerosol with high automation degree and good stability.
