Product Details
Laser Safety Class IEC 60825-1 (2014) Class 1M Eye Safety Wind Lidar
1,Product introduction
It can be known from the Doppler principle that the Doppler frequency shift fd of the echo signal is proportional to the moving speed of the aerosol particles (that is, the wind speed), so the backscattered signal received by the optical antenna passes through the local oscillator generated by the fiber laser inside the system.The light beat frequency in the coherent detection module and the digital demodulation can be processed to obtain the wind speed information of the target area to be measured.
