Dust flow analysis by low coherence Doppler lidar
Scientific Reports, 2023 AbstractVisualization of dust flow and wind dynamics near the ground surface are essential for understanding the mixing and interaction between geosphere and atmosphere near the surface. Knowing the temporal dust flow is beneficial in dealing with air pollution and health issues.

Coherent Random-Modulated Continuous-Wave LiDAR Based on Phase-Coded Subcarrier Modulation
Photonics, 2021 A coherent random-modulated continuous-wave (RMCW) LiDAR transmits a lightwave modulated by a pseudo-random binary sequence (PRBS). The lightwave backscattered from targets is received and used to reconstruct the PRBS.

Thundercloud structures detected and analyzed based on coherent Doppler wind lidar [PDF]
Atmospheric Measurement Techniques, 2023 The studies of intracloud discharges may shed light on the microphysical structure of thunderclouds, as both the magnitude and the sign of charge separation due to graupel collides with ice crystals within the strong updrafts are influenced by the ...

Aircraft Wake Vortex Measurement with Coherent Doppler Lidar
EPJ Web of Conferences, 2016 Aircraft vortices are generated by the lift-producing surfaces of the aircraft. The variability of near-surface conditions can change the drop rate and cause the cell of the wake vortex to twist and contort unpredictably.
