Lidar Stabilization

University of Notre Dame Lidar Motion Stabilization System

The LiDAR Stabilization Platform is used on research vessels to keep the Halo Photonics Streamline scanning Doppler LiDAR level while taking data.  The platform was designed in-house with help from Perfect Horizons Camera Stabilization Systems in Venice, California. Motion stabilization provides capability to scan the Lidar laser beam at a constant elevation above the sea level without the contamination of vessel’s pitch and roll. Measurements of marine boundary layer wind profiles with high temporal resolution are presented for multiple research cruises.  The Lidar retrieved wind speed and direction have been evaluated against radiosondes data.  The accuracy of platform stabilization in both pitch and roll was found to be within 0.5 degrees throughout the CASPER field campaigns.  Instantaneous horizontal wind speed root-mean square error (RMSE) of 1.3 ms-1 and wind direction RMSE of 6.5 degrees were observed when compared with radiosonde observations.
