Embodiment 1
[0023] like figure 1 Shown: a measuring device for aerosol lidar ratio, including a laser beam light source 1, an attenuation sheet 2, a spectroscope, an aerosol containing space 10 and a light energy detector, the attenuation sheet has a transmittance of 0.01, and is located on a laser beam Between the beam light source 1 and the beam splitter, it is used to attenuate the energy of the laser beam. The laser beam source 1 produces a laser beam that passes along one side of the aerosol accommodating space 10. The first beam splitter 4 and the second beam splitter 6 on the side, the first beam splitter 4 splits the laser beam and makes the reflected light enter the aerosol accommodation space 10, and the second beam splitter 6 passes through the aerosol accommodation space 10 The reflected light is split again, and the light energy detector includes a first detector 5 for measuring the transmitted light energy of the laser beam passing through the first beam splitter 4, and a se...
