Doppler Lidar

We are Continuous Wave

Doppler Lidar is a proven means of measuring the line of sight wind speed of aerosols found naturally (dust, water, pollution) traveling in the wind, by calculating the Doppler shift – the change in frequency of our omitted laser wave – of the light reflected, or ‘backscattered’, by the aerosols.

Up to 50 line of sight measurements are made every second ensuring high quality, high availability wind information, unique to Continuous Wave Lidar.

Measurements every 20 milliseconds freeze out motion encountered when our Lidar is mounted in turbines or on floating buoys.

Taking so many measurements, in a conical scan pattern, increases the chance of returning a valid wind signal when working in challenging environmental conditions or when part of the scan is blocked by a fixed object.

Our optimised probe volume, as short as just 7 cm, captures rapidly changing wind flows experienced close to ground level, around structures and even in wind turbine induction zones.

Our true Class 1 eye-safe laser beam is focused at every desired measurement height / range ensuring that availability of this extensive data set is further maximised with constant sensitivity at all heights.
