Wake vortex detection and monitoring
Aerospace Science and Technology, 2002Abstract Coherent laser radar (CLR) or lidar is a powerful technique for the detection and study of aircraft wake vortices. The technique measures the Doppler shift of light scattered from atmospheric particles, and hence infers the line-of-sight flow velocity allowing a picture of vortex flow to be built up.

Ship wake detection by Raman lidar
Applied Optics, 2010We carried out a remote study of ship wakes by optical methods. Both Mie and Raman scattering signals and their evolution were simultaneously recorded by gated detector (intensified CCD). The Mie scattering signal was detectable within 1 min after water disturbance by a high-speed boat.

Simple lidar detecting wake profiles
Journal of Optics A: Pure and Applied Optics, 2007A simple lidar to detect wake profiles based on laser backscattering by bubbles at 180° is reported. The monostatic optical geometry is adopted in this lidar and a theoretical model for measuring light scattered backwards by bubbles at 180° is given.
