Abstract: An optical detection system uses high-resolution holographic filters for target detection within a very-large field of view image acquired with a reflector. The holographic filter acts as an optical computer, mixing phase and amplitude information of known targets with light from the scene, automatically enhancing portions of the image that match threat objects or other object of interest. A lens forming a Fourier transform of the entire scene is used, and within that transform, the holographic information of a target or multiple targets is added. By acting as an inverse optical transfer function, the hologram gathers the target information to single point, and removes non-target background. Amplification is done by using a laser-illuminated hologram to create a phase-amplitude filter in a photorefractive material at the transform plane. By mixing the hologram and the scene at the transform plane, the matching is enhanced regardless of target location in the scene.

Abstract: A laser transmission assembly for shearography and related systems utilizing transmissive geometric phase plate pairs in place of Risley prism pairs or movable mirrors therein. Transmissive geometric phase plates provide for a system that is more compact than systems utilizing mirrors or Risley prism pairs while maintaining or improving the adjustability of the system and further offering beamshaping to provide desired illumination patterns.

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: Systems and methods for computationally simulating an optical image are provided. The systems and methods generate a simulated scene having at least one variable optical property, compute an optical transfer function (OTF) via at least one computed phase screen, express the OTF as a sum of at least one separable OTF, convolve the at least one separable OTF with the simulated scene to simulate electromagnetic (EM) fields of the optical image, and compute image intensities of the optical image from the simulated EM fields of the optical image.

Abstract: An object detection system uses a change in a linear polarization statistic between a first image at a first time and a second image at a second time to determine the presence or the likelihood of an object beneath a surface. The presence of the object may be determined by regions of anomalously high changes in the polarization statistic. The system may use a polarization change detection detector which may simultaneously capture images in multiple polarization channels. Further, the polarization change detection detector may be coupled with a laser interferometry system.

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.
