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.
