Paper Abstract

The use of Adaptive Optics (AO) to correct for aberrations in a wavefront of propagating light has become customary for Astronomical applications and is now expanding to many other areas going from medical imaging to industrial applications. However, the propagation of light underwater has remained out of the main stream AO community for a variety of reasons, not least the shear difficulty of the situation. Our group has become a program that attempts to define under which circumstances such a correction could be envisioned. We take advantage of the NRL laboratory facility in Stennis, MS, where a large Plexiglas tank of water is equipped with heating and cooling plates that allow for a well measured thermal gradient that in turn generates different degrees of turbulence that can distort a propagating laser beam. In this paper we report on the preliminary findings of this ongoing program. The paper will describe the facility and the AO test-bed, the measurements made and some of the preliminary result.
