Effect of penetration depth and swell-generated tilt on delta-k lidar performance.
Delta-k lidar can be used to measure the amplitudes of small waves on the surface of the ocean as long as the tilt of the surface is known. This tilt can be inferred from Δk measurements at orthogonal polarizations. The wavelength of the lidar must be chosen so that the penetration depth of the light is much less than the length of the surface wave being measured; otherwise, the Δk signal will be reduced.
