doppler wind lidar Nacelle Wind Lidar Molas NL four beam Bankable
| Product introduction
Molas NL series is a nacelle wind lidar independently developed for the intelligent application scheme of wind power customers. It is a laser remote sensing wind measurement device installed on the top of the wind turbine nacelle. The lidar adopts the coherent detection system, and based on the principle of laser Doppler frequency shift, realizes the accurate measurement of 50m-200m / 400m / 750m vector wind field in front of the fan impeller.
The working principle of wind lidar is shown in the following figure. The signal light generated by the fiber laser is emitted into the air to be measured through an optical antenna, and interacts with the aerosol particles to generate a backscattered signal containing their velocity information.
