Abstract: An underwater imaging system is carried by a submersible platform to capture images that are processed into three-dimensional images stitched together to create a 3D dimensional video at video rate speeds that are transmitted to a control unit above the surface of the water. The imaging system utilizes a high speed image sensor or camera to capture sequential gated images that are synced via a gating module to two sequential laser beam pulses. The laser beam pulses illuminate an object in each gated image. When the object is within a gate overlap region, the two images may be processed using 3D imaging techniques to generate a 3D representation of the object in the overlap region of the two gates.

Abstract: A system and method is provided to characterize optical properties (Scattering, attenuation, de-polarization) of a light-transmitting medium and local environment, by determining a scattering rate of light through a medium, wherein determining the scattering rate of light through the medium is accomplished by utilizing polarized light transmitted from an optical source. The system and method performs a function based on the characterized optical properties of the medium, wherein the function is one of, for example: detection of objects embedded in the medium, object ranging through the medium, or deblurring of images acquired through the medium.
