Description
technical field [0001] The invention relates to the technical field of water detection structures, in particular to a detection element with active vibration reduction. Background technique [0002] Lidar technology is a brand-new remote sensing technology. Because of its high precision and high efficiency, it has developed rapidly in topographic surveying and mapping. It plays an important role in pipeline design, aircraft and shipbuilding and other fields. Lidar technology can carry information with phase, frequency, polarization and amplitude, and obtain the spatial geographic information of the target in real time. [0003] At present, the LiDAR technology has been combined with the shipborne multi-beam bathymetric technology, and the water-borne carrier has been used for integrated measurement of water and land, which puts forward higher requirements for the stable and simple installation of the LiDAR. [0004] The existing ship-borne lidar installation device only us...
