The ability of light to penetrate the sea to operationally useful depths, the ease with which optical energy can be generated and modulated, and the ability to direct this energy into narrow beams utilizing small antennas optical systems illustrate the theoretical feasibility of optical communication links in the sea. For example, when the proportionate sea path is limited to lengths of hundreds of feet or meters, optical communication links between an earth orbiting satellite and submerged terminals appear possible. Before such optical communication links become practical, phenomena reported in the literature must be quantified to reliably predict system performance. This is necessary for systematic design and evaluation of terminals. For example, optical beam spreading, attenuation, airsea interface effects, and background radiant intensities must all be documented to be used for component development. With these objectives in mind, an experiment designed to measure the propagation characteristics of light in the ocean was conducted in the vicinity of Santa Catalina Island, California, between June and August 1975.
