Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] Referring to FIG. 1 , the multifunctional atmospheric lidar in the present invention mainly includes: a laser transmitter 1 , an optical receiver 2 , and a photoelectric detector 3 .

[0014] Referring to Fig. 2, laser emitter 1 is made up of laser 4 (Continuum, model Powerlite-9020), reflecting prism 5 (Newport, model 10SR20) and three-dimensional adjustment prism holder 6 (Newport, model UGP-1); Laser 4 output ends and The input ends of the reflection prism 5 are connected, and the reflection prism 5 is installed on the three-dimensional adjustment prism frame 6 . Add frequency doubling and frequency tripling in the configuration of laser 4 (the accessory that laser 4 carries), laser 4 outputs the pulsed laser beam of 1064nm, 532nm and 266nm, reflective prism 5 deflects laser beam 90 ° and makes it vertical upward emission, The three-dimensional adj...

Abstract

This invention relates to a kind of multifunctional laser radar, including a laser transmitter used for emitting the pulsed laser beams of 1064nm, 532nm and 355nm to the atmosphere, an optical receiver used for receiving the scattered echo of the laser beam, a photodetector used for processing the optical signal echo. The laser transmitter is composed of a laser, a reflection prism and a 3D regulating frame for the prism. The output of the laser connects with the input, and the reflection prism is installed on the 3D regulating frame. The laser is a kind of Nd:YAG laser which can outputs the laser beam of 1064nm, 532nm and 355nm.

Description

technical field [0001] The invention relates to a multifunctional atmospheric laser radar capable of measuring various important atmospheric parameters. Background technique [0002] Atmospheric aerosols and clouds, trace gases such as ozone, and water vapor have a strong impact on the radiation budget of the entire earth-atmosphere system, the global environment, and global climate change. Therefore, the detection and research of the characteristics of the above atmospheric parameters is an important topic in atmospheric science. At the same time, the detection research on the spatial distribution and temporal variation of the above atmospheric parameters is also of great significance in practical application fields such as the study of atmospheric optical characteristics, laser atmospheric transmission, and atmospheric correction of satellite remote sensing data. At present, some microwave radars and lidars that detect atmospheric parameters have appeared, but they can on...
