Description
Technical field [0001] The invention relates to the technical field of atmospheric and environmental monitoring equipment, in particular to a laser emitting device for laser radar. Background technique [0002] Lidar is an active remote sensing monitoring equipment, which has the advantages of high temporal and spatial resolution and high measurement accuracy. In recent years, with the development of laser technology and photoelectric detection technology, lidar has gradually been applied to the detection and research of the middle and upper atmosphere. In order to meet the requirements of lidar for measuring the three-dimensional wind field in the upper atmosphere, the lidar transmitter system is required to simultaneously emit laser beams in three directions (such as vertical, east, and north), and to achieve high-precision adjustment of the three beam directions , To ensure the collimation of the receiving and emitting axis in each direction. [0003] The existing lidar transm...
