Abstract:

The patent relates to an apparatus for monitoring the underwater luminous field with an underwater vehicle, to determine, while submerged, the conditions of sea surface and cloud cover and locate the vehicles position by solar navigating techniques. The apparatus measures underwater polarization of solar light in magnitude and its spatial distribution as a function of time and thus determines the condition of sea surface and cloud cover, while submerged at operational depths.
