    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: The present disclosure provides a system and method for determining a range to an object in a fluid. The system includes a polarized light source directed to the object in the fluid, a first imaging sensor, a second imaging sensor, and at least one processor. The at least one processor characterizes a depolarization rate of the fluid and determines the range to the object. The method includes generating polarized light via a polarized light source, polarizing an imager relative to the polarized light, transmitting the polarized light from the polarized light source into the fluid, receiving reflected light from the object, characterizing a depolarization rate of the fluid, based, at least in part, on the reflected light, and determining the range to the object, based, at least in part, on the depolarization rate of the fluid.

    Abstract: Systems and methods for computationally simulating and optimizing shearography systems are provided. The systems and methods for simulation and optimization avoid ray tracing, and, instead, implement a phase screen approach to image computation. The systems and methods include physics-based surface texture and surface motion simulations, the application of phase screens to computer-generated simulations of shearographic remote sensing, and the inclusion of de-polarization due to multiple scattering and birefringence at a surface being imaged. The systems and methods include further greatly optimize diffraction computations by treating an optical transfer function (OTF) of an arbitrary aperture as a sum of separable OTFs.

    Abstract: A shearography system and method provide advances allowing for rapid processing to produce shearograms which provide surface motion information which may be helpful in multiple fields. For instance, amongst virtually endless possibilities, the system and method may allow for detection of underground structures or ordnance and or be used in the medical field to provide non-contact sensing of a person's internal structures or movements.

    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.
