Measurement device for measuring aerosol parameters by lateral laser radar

Abstract

The invention belongs to the technical field of aerosol measurement, and particularly relates to a measurement device for measuring aerosol parameters by a lateral laser radar. The measurement device comprises a base; the upper side of the base is provided with a horizontal rotation mechanism; the upper side of the horizontal rotation mechanism is provided with a pitch mechanism; the upper side of the pitch mechanism is fixedly provided with a CCD lateral laser radar mechanism; the CCD lateral laser radar mechanism comprises a CCD camera and a laser radar for transmitting laser beams; the CCD camera is arranged at the upper side of the laser radar; and the medial axis of the CCD camera lens is parallel with the direction of the laser beams transmitted by the laser radar. In the case of work, the laser radar and the CCD camera rotate synchronously in the horizontal direction through the horizontal rotation mechanism, the laser radar and the CCD camera rotate synchronously in the vertical direction through the pitch mechanism, and actions of a transmitting device and a receiving device in the CCD imaging lateral laser radar can be ensured to be kept consistent.

Description

technical field [0001] The invention belongs to the technical field of aerosol measurement, and in particular relates to a measuring device for measuring aerosol parameters by lateral laser radar. Background technique [0002] CCD imaging lateral lidar is a new technology being researched internationally. It places the transmitting device and the receiving device in two places, and uses the signal strength of different pixels in the CCD camera to record the lateral position at different distances on the emitted beam. Scattered light intensity. The vertical distance from the CCD camera to the emitted beam is generally 5-200m, and the opening angle of the CCD camera can reach 90 degrees. In this way, the beam range that the CCD camera can detect can reach 0-5km. [0003] In order to obtain accurate measurement results, it is necessary to achieve good action cooperation between the transmitting device and the receiving device in the CCD imaging side-facing lidar, that is, the...

Problems solved by technology

[0003] In order to obtain accurate measurement results, it is necessary to achieve good action cooperation between the transmitting device and the receiving device in the CCD imaging side-facing lidar, that is, the actions of the two must be coordinated. In the prior art, the transmitting device and the receiving device The actions between the two devices are often difficult to keep synchronized, making it difficult to obtain accurate measurements
