Optimizing Scan Homogeneity for Building Full-3D Lidars based on Rotating a Multi-Beam Velodyne Rangefinder [PDF]
Multi-beam lidar (MBL) scanners are compact, light, and accessible 3D sensors with high data rates, but they offer limited vertical resolution and field of view (FOV). Some recent robotics research has profited from the addition of a degree-of-freedom

Scanning lidar bathymeter for water depth measurement
A scanning lidar bathymeter has been developed for airborne hydrographic surveying. The system has a depth penetration capability of four optical diffuse attenuation lengths, with an accuracy of ±0.3 m.From an altitude of 500 m the system generates a swath 270 m wide and a uniform sounding density on a 35 m grid spacing with a positioning accuracy of ∼
