Abstract

The spatial and angular structure of light radiance in the depth of seawater can be precisely computed with such numerical programs like Hydrolight. Unfortunately such calculations demand a lot of computational time if used for problems of visibility of submerged objects. In this case, due to the much greater computational efficiency and logarithmic dependence of visibility parameters on radiance values, analytical radiative transfer methods are preferable. In this presentation a new analytical radiative transfer method is proposed to solve visibility problems in seawater. The angular structure of depth-dependent light radiance in the sea is obtained in the framework of previously published selfconsistent approximation. The analytical expressions proposed in this paper allow to compute a horizontal visibility of submerged objects. This approach can be applied to problems of diver visibility in shallow water bodies of arbitrary turbidity and illumination.
