Abstract

An eye-safe turbulent UV (355 nm) lidar BSE-5 designed for the study of atmospheric turbulence is described. Lidar works on the basis of the backscatter enhancement effect, which occurs when a light wave propagates twice in a random medium. The design of the lidar is based on a transceiving afocal Mersen telescope, which supports thermomechanical stability during long-term operation of the device. To reduce the telescope size, the edges of the primary mirror have been cut off, because they are not used during the lidar operation. The lidar was tested at Tolmachevo airport, Novosibirsk. During the tests, the turbulence was continuously monitored over a runway and over the aircraft parking. The lidar confidently recorded a turbulent wake of any aircraft during takeoff and landing. The lifetime of a strong artificial turbulence over the airfield was found to be 2–3 min.

湍流紫外线激光雷达BSE-5

摘要

描述了设计用于研究大气湍流的人眼安全的湍流紫外线（355 nm）激光雷达BSE-5。激光雷达基于反向散射增强效应工作，这种反向散射增强效应是在光波在随机介质中传播两次时发生的。激光雷达的设计基于收发式共焦Mersen望远镜，该望远镜在设备长期运行期间可支持热机械稳定性。为了减小望远镜的尺寸，已切除了主镜的边缘，因为在激光雷达操作期间未使用它们。激光雷达在新西伯利亚的托尔马切沃机场进行了测试。在测试过程中，在跑道和飞机停放处不断监测湍流。激光雷达自信地记录了起飞和降落期间任何飞机的湍流尾迹。
