Abstract : The patent describes an improved underwater, remotely-controlled camera equipped with a coupled illumination system. The illumination system incorporates spaced light beam sources which are steered and focused to illuminate the field of view of the camera. Additionally, the light sources are equipped with polarization filters to polarize the light so as to cooperate with a similar device on the camera to eliminate backscattered light from particulate matter in suspension in the water between the camera and the object being viewed.
