Abstract:
The present invention concerns motion-stabilised LIDAR (100), MS-LIDAR, for measurement of wind speed, comprising: a stabiliser unit (25) having a having a probe end (30) for attachment to a laser radar, LIDAR (10), and a base end (40) for attachment to a buoyant platform (80), which stabiliser unit (25) is configured for at least partial isolation of motions of the base end (40) from the probe end (30); a LIDAR (10), attached in fixed relation to the probe end (40); a motion detector in fixed relation to the probe end (30); which MS-LIDAR (100) is arranged to make wind speed measurements at one or more remote probe volumes.
