Abstract

Until recently, little has been done to study the effect of higher modulation frequencies ($>100\mathrm{MHz}$) or short ($<2\mathrm{ns}$) pulse durations on forward-scattered light in ocean water. This forward-scattered light limits image resolution and may ultimately limit the bandwidth of a point-to-point optical communications link. The purpose of this work is to study the propagation of modulated light fields at frequencies up to $1\mathrm{GHz}$. Results from laboratory tank experiments and their impact on future underwater optical imaging and communications systems are discussed.
