Optical Surveillance: Beam Attenuation in Naval and Underwater Defense Applications - Sequoia Scientific

In the underwater world, visibility is everything. Whether it’s a diver navigating murky waters, an autonomous vehicle scanning the seafloor, or a naval operation relying on optical sensors, understanding how light behaves underwater is critical. A simple and powerful measure for assessing underwater visibility is the beam attenuation coefficient (c) — a measure of how much light is lost due to absorption and scattering as it travels through wat…
