Molas NL 4 Beam Wind Lidar
Wind Lidar System Molas NL Adopts a 4-beam optical scheme
1,Summary
Molas NL series is a nacelle-type wind measurement lidar independently developed by MOVELASER for intelligent application solutions of wind power customers. It is a laser remote sensing wind measurement device installed on the top of the wind turbine nacelle. The radar adopts a coherent detection system and based on the principle of laser Doppler frequency shift, it can accurately measure the wind vector field 50-200m/400m in front of the fan impeller.
