Nacelle-mounted wind-measurement lidar ATOM-Lidar-T400
Zhongke Yuanzi's nacelle-mounted coherent Doppler wind lidar is installed on top of a wind-turbine nacelle. It measures Doppler shifts in atmospheric returns of pulsed laser light to obtain wind profiles within 400 meters ahead of the blades. It provides a reliable, efficient solution for feedforward turbine control, improving efficiency and reducing loads, and can also be used for wind-power testing and wake monitoring. The lidar performs coherent heterodyne detection between a single-frequency local-oscillator signal and aerosol-backscattered laser light. Doppler frequency shifts determine radial wind speed. Multibeam scanning measures wind speed in several directions to reconstruct real-time wind-field data.

905nm Laser Module for Lidar BGFL-905-MF-FP
LiDAR
Bogaolaser
Center wavelength λc [25℃]: typical:905 nm Output Efficiency [25℃]: min:60%；typical:65%；max:70% Spectral width △λ [25℃]: typical:5 nm
This product uses a TO package. A bonded self-focusing lens ensures efficient coupling of the LD laser into the fiber. The pigtail terminates in a common FC/APC or FC/PC connector, compatible with most fiber adapters, fiber collimating lenses and fiber focusing lenses for convenient integration. Applications include laser ranging, laser sensing and lidar. Advantages include compact construction, high efficiency and long-term reliability. When using this LD laser series, identify the LD + and - pins correctly and strictly avoid excessive current. Short the + and - pins after use to prevent damage from ambient electrostatic discharge.
