What is Doppler Lidar?
The abbreviation "Lidar" means the detection and range of light. Where the radar uses radio waves to determine the range or distance of the object, Lidar uses light in the form of laser for various measurements. Using either pulsating or continuous laser beams to measure changes at light frequency and other factors, Lidar Laser technology is used in various applications. In particular, Doppler Lidar measures wind speed with both pulsating and continuous laser beams. Measurement as scientists and meteorologists can determine the wind speed and other related data by measuring the frequencies of laser light shifts.
both Doppler Radar and Doppler Lidar are useful tools for determining weather conditions. For example, the scanning Doppler Wind Lidar, known as Harlie Lidar, can be used to measure wind speed at the atmospheric level. In 2008, the Olympic Yacht competition took advantage of the Doppler Lidar technology to measure wind fields. Meteorologists used for the Olympic tournamentThe supply of Chinese scientists who help to provide up -to -date information on wind conditions, speed and direction.
with technology and equipment Doppler Lidar, scientists, scientists and meteorologists broadcast laser at a predetermined, set frequency. The frequency moves when the laser light collides with various molecules and aerosols in the air. When light returns to the receiver, changes in the light frequency help scientists determine specific factors such as speed and direction. The images appear on the monitor with high spatial and time resolution.
Research and improvement Doppler Lidar continued. Such technology is planned for use in weather forecasts, military applications and aviation. Having such targeted and clear displaying wind conditions provides a lot of information necessary for public security. Administrators will use the data providers of wind speed for public planningof severity during serious weather conditions. Aviation and military agencies will use this technology to determine the flight conditions long before the crews or equipment fly away.
