Abstract: The system and method for accurately determining range-to-go for the command detonation of a projectile warhead. Using dual laser detectors on the tail and on the nose of a spinning projectile to determine the range-to-go, time-to-go, or lateral offset from the projectile to the target. The method for controlling a projectile warhead uses a large area PIN detector and an ogive window. If the PIN detector is large enough to capture the second laser signal, the window is no longer an optical element, only a window thereby drastically reducing the cost of the system. In some cases the detector on the nose of the projectile comprises several PIN diodes placed around the projectile as a distributed aperture. Distributed apertures may also be created by placing the PIN diodes on the wing roots or body of the projectile.

Abstract: The system and method of sensor imager and laser alignment. The system utilizes a DLP mirror array with a compact collimator to provide a real time, direct mapping of the laser energy from a LRF onto an imager (e.g., visible, SWIR, LWIR, or the like) by using a back scatter approach. This method eliminates the thermal and vibration/shock optical alignment issues by using a relative measurement approach significantly reducing the size, weight, and cost of the alignment system.

Abstract: An apparatus for securing an image sensor within a night vision scope is disclosed. The apparatus includes a flat washer, a crush bushing, and a fastener. The crush bushing is inserted through an opening of a corner anchor of the image sensor. A fastener receptacle is located at a module of the night vision scope. The fastener can be inserted through an opening of the flat washer and a bore of the crush bushing to deform the crush bushing such that the crush bushing material fills any space between the fastener and the fastener receptacle, thereby creating a zero-play connection to restrict any slight movements generated by shocks and vibrations.

Abstract: A system and method for imaging a sample having a complex structure (such as an integrated circuit) implements two modes of operation utilizing a common electron beam generator that produces an electron beam within a chamber. In the first mode, the electron beam interacts directly with the sample, and backscattered electrons, secondary electrons, and backward propagating fluorescent X-rays are measured. In the second mode, the electron beam interrogates the sample via X-rays generated by the electron beam within a target that is positioned between the electron beam generator and the sample. Transmitted X-rays are measured by a detector within the vacuum chamber. The sample is placed on a movable platform to precisely position the sample with respect to the electron beam. Interferometric and/or capacitive sensors are used to measure the position of the sample and movable platform to provide high accuracy metadata for performing high resolution three-dimensional sample reconstruction.

Abstract: Improved binocular vision system having a high resolution, uncompressed image in the forward facing direction and compressed images on the left and right side periphery. The binocular vision system utilizes a shared sensor between multiple optics to reduce the cost and weight of the device. The system maps multiple optics to portions of sensor arrays such that the compression on the periphery is in the azimuth only and thus more closely matches human vision.

Abstract: A counter measure system is provided having a unitary infrared transparent dome including a look angle greater than 180. The dome has two hemispherical regions, with a second region having a truncated bottom end defining an opening to a central cavity inside which electro-optical elements are disposed. The electro-optical elements can view outward through the dome at the look angle. The second region on the dome has a complementary curvature as the first region by continuing a similar radius beyond a transverse horizontal axis or equator. The dome is mounted to a base, which also may be referred to as a bezel. The base defines a rabbet extending circumferentially about the base imaginary center defining an aperture. The base and the dome are formed from different materials but have equivalent coefficients of thermal expansion. In one embodiment the dome if formed from sapphire and the base is titanium.

Abstract: The system and method of implementing a high reliability flash memory recorder comprising warm spare and error code correction bytes across several multi-chip modules. The use of redundant field programmable gate arrays and/or processors for command and control increases redundancy. The system and method has lookup table-based mechanisms combined with programming to determine when to substitute a warm spare byte as well as when to declare a block of memory as “bad” and no longer to be used. The system may use multiple memory banks with power switching per bank to reduce power consumption as well as increase reliability when the array is not being accessed.

Abstract: A motion compensation system for a shearography apparatus includes: an adjustable first fold mirror to reflect laser radiation to a receiving aperture of the shearography apparatus during separate pulse periods at corresponding angles of reflection; and corresponding second fold mirrors to reflect the laser radiation from a target surface to the first fold mirror during the respective pulse periods. The shearography apparatus moves with respect to the target surface between the separate pulse periods. The angles of reflection make the laser radiation reflected from the target surface via the respective second fold mirrors appear to the receiving aperture as if the shearography apparatus is stationary with respect to the target surface. In another system, the second fold mirrors are replaced by an adjustable second fold mirror to reflect the laser radiation from the target surface to the first fold mirror during the pulse periods at corresponding second angles of reflection.
