Paper Abstract

Optical imaging in turbid ocean water is a challenge due to the high probability that light will scatter multiple times as it propagates to and from the object of interest. Techniques have been developed to suppress the contribution from scattered light and increase the image contrast, such as those using a pulsed source with a gated receiver or a modulated source with a coherent RF receiver. While improving the amplitude contrast of underwater images, these two approaches also have the capability of providing target range information. The effectiveness of each approach for both 2D and 3D imagery depends highly on the turbidity of the intervening water medium. This paper describes a system based on the optical modulation approach, the Frequency Agile Modulated Imaging System (FAMIS), and the techniques that have been developed to improve both amplitude and range imaging in turbid water.
