Regional atmospheric transmittance and particle spectrum three-dimensional distribution detection device and method

The invention discloses a regional atmosphere transmittance and particle spectrum three-dimensional distribution detection device and method, and relates to the technical field of environmental monitoring, the regional atmosphere transmittance and particle spectrum three-dimensional distribution detection device comprises a detection mechanism and a scanning unit used for adjusting the detection mechanism, the detection mechanism is installed on the scanning unit, and the scanning unit is used for adjusting the detection mechanism. The scanning unit drives the detection mechanism to do horizontal and vertical rotation motion; the laser emitting unit emits laser, the signal receiving unit is used for receiving scattering signals generated by the laser emitted by the laser emitting unit, the scattering signals received by the signal receiving unit are converted into electric signals through the photoelectric conversion unit, and the electric signals are received and stored through connection of the data acquisi
