Optical vortex asw lidar

WebLiDAR employs 2D laser scanning to access 360° of panoramic data in the horizontal (azimuth) plane and a vertical field of view (FOV) of up to 40°. The laser scanner (Figure 1) uses the time of return (time-of-flight) on each pulse to determine the range (slant) distance to the object. The X Y Z coordinates of each return are calculated and ... WebAn onboard LIght Detection And Ranging (LIDAR) sensor designed to track wake vortex created by aircraft in formation flight is presented. It uses short pulses (75 ns) to obtain a spatial resolution of ∼22.5 m required to resolve small-scale structures of vortices and a blind zone of 17.5 m to locate vortices next to the wing tip.
