A Laser-Based Surface Reconstruction Device for Oceanographic Measurements

Abstract

The water surface is formed by larger gravitational waves as well as smaller capillary waves superimposed on the gravitational waves. The primary goal of this project is to design, build and field test a device suitable for obtaining the shape, and in particular, the slopes of the larger waves. The target application for this device is an LIDAR-based system, mounted on a helicopter, used for detecting underwater targets. By using the slopes provided by the device, it will be possible to correct for the refraction distortions due to the gravitational waves and obtain a more accurate location estimation of the target.
