Doppler Lidar Systems

Products – Compact Optical-fiber Doppler Lidar System

Being compact, light, and portable, it provides wind profile measurement which fits the user’s need

Main Features

  • Processes atmospheric conditions up to a horizontal distance of 3km* horizontally.
  • Unlike radar that measures precipitation, the wind speed can be measured when there is no precipitation.
  • Class 1M laser with eye-safe wavelength.
  • All laser circuits are connected using optical fiber, making the system easy to move and set up.

(* Actual observation range varies according to the aerosol condition of the atmosphere.)


  • Meteorological observations (vertical profiling of atmospheric wind, local wind measurement)
  • Urban disaster/safety (measure building-wind, sudden wind gusts on highways, small aircraft crosswinds)
  • Air environment consultation (urban heating, monitoring of substances released in emissions from factories, investigating wind conditions for wind power generation, estimating power generation output)
