Design of Systems for Underwater Optical Imaging in the Presence of Particulates

Lei Tian, Jonathan C. Petruccelli, Jason S. Ku, Xiaogang Liu, George Barbastathis


This paper presents two kinds of techniques that can be used for underwater imaging. They are designed for different flow conditions. The first one, digital holography, is a three-dimensional imaging technique that can be used to characterize the flow when the particles inside the flow are sparse. The other technique, light field imaging, is another three-dimensional imaging technique that allows the extraction of information about an object obscured by dense distributions of particles. Experimental setups and results are presented.
