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 coded image system enables a user to recover an object scene from an encoded image. The coded the image system comprises: a physical object scene; an encoding logic creating an encoded image, the encoding logic including a programmable aperture mask spaced a distance away from the physical object scene to encode the encoded image via a doubly-Toeplitz matrix, the doubly-Toeplitz matrix including two one-dimensional vectors; and a decoding logic operatively coupled to the programmable aperture mask to decode the encoded image recovering a visual representation of the object scene from the encoded image.

Abstract: An interferometry system and method thereof detects movements of the surface of a body of water in response to acoustic waves generated from a sub-surface source interacting with the surface. Movements of the surface of the body of water are viewed over multiple interferometric images that can be pieced together to generate an interferometric movie or video. The interferometric movie or video depicts the movement of the acoustic wave propagating through the viewing area. Once the movement of the acoustic wave propagating through the viewing area is known, then back propagation techniques are employed to determine or triangulate the location of the sub-surface source that generated the acoustic wave.

Abstract: A self-localizing autonomous underwater vehicle swarm that is operable to accurately localize each individual unit within the swarm while only requiring a single node at a known location to do so. The methods described herein can localize all members of a swarm with minimal, if any, effect on the size, weight, power, and cost of a system.

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.
