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 soft-kill countermeasure system utilizing a confirmation device, which may be radar, to enhance existing countermeasures, and enable new countermeasures to be utilized to combat the ever evolving and increasing sophistication of threats. The threat defeat confirmation may allow for rapid or immediate redirection of the countermeasure system to address additional simultaneous threats. The confirmation device can be mounted on a gimbal head or above a gimbal to take advantage of slewing movement to direct the confirmation signal towards the threat.

Abstract: A laser mast for attachment to a ground vehicle includes a mast, a rotary stage, a platform, a first laser, and a second laser. The rotary stage is connected to and rotates the mast. The platform is connected to the rotary stage. The first laser is within the mast. The second laser is within the rotary stage or the platform.

Abstract: A soft-kill countermeasure system utilizing a tracking radar to enhance existing countermeasures and enable new countermeasures to be utilized to combat the ever evolving and increasing sophistication of threats. The use of the tracking radar may further allow for immediate threat defeat confirmation which may allow for rapid or immediate redirection of the countermeasure system to address additional simultaneous threats.

Abstract: The system and method of pupil size independent pupillometry used for assessing critical diagnostic characteristics relating to neurotransmission and neuroactivity as applied to toxin exposure. The system and method utilizes the timing of a response to stimuli for a pupil of an individual, characterizes the timed responses, determines the latency of the timed responses, measures the minimum constriction value for the timed responses; and assesses the timed responses collected to diagnose changes in neurotransmission and neuroactivity for an individual exposed to organophosphate (OP) nerve agents or botulinum toxin (BTX).

Abstract: The system and method of size independent pupillometry used for assessing critical diagnostic characteristics relating to traumatic brain injury (TBI). The system and method utilizes the timing of a response to a stimuli for one or more pupils of an individual, characterizes the one or more timed responses, determines the latency of the one or more timed responses, measures the minimum constriction value for the one or more timed responses; and assesses the one or more timed responses collected to detect changes in neurotransmission and neuroactivity of an individual to assess the presence of a traumatic brain injury.

Abstract: Techniques are provided for detection, classification and tracking of surface contacts based on multispectral image data from sensors on maritime assets. An example system may include an anomaly detection circuit configured to detect an object based on anomalies in the variance of pixels of water surface image data. The system may also include an object motion tracking circuit configured to analyze motion of the object relative to water surface waves. The analysis may compensate for motion of the asset and sensors. The system may further include an object classification circuit configured to classify the object as an object of interest, based on the analyzed motion of the object, and as a threat, further based on size estimation, edge detection, surface texture analysis, and volume analysis. The range from the asset to the object may be estimated based on the relation of the object to a detected or estimated horizon line.

Abstract: Techniques are provided for estimating the direction of a laser source under non-uniform illumination conditions such as laser speckle. An example system may include a detector array comprising sensors configured to detect the amplitude of the received laser signal. The sensors are disposed on the array at unique orientation angles relative to each other. The sensor size is selected based on the speckle pattern of the laser signal such that the sensors are small enough to be uniformly illuminated by the laser signal in the presence of speckle. The system also includes an amplitude ratio calculation circuit configured to calculate ratios of the amplitudes between each of two sensors of one or more pairs of sensors. The system further includes an angle of arrival calculation circuit configured to estimate the direction of the source of the laser signal based on the calculated ratios and the orientation angles of the sensors.
