A coherence reconstruction apparatus generates measurements of atmospheric turbulence from light reflected by a target. The apparatus is in communication with a coherent beam combining (CBC) system which illuminates a target with one or more partially coherent beams from a seed laser. The apparatus includes a variable delay module and a phase shift interferometer (PSI). The delay module uses a measurement of target time-of-flight to form a coherent delayed reference signal from the CBC seed reference laser. The delay module may incorporate an electromagnetically induced transparency medium and/or an electro-optical modulator. The PSI combines the delayed reference optical signal with a target-reflected optical signal to form an interference pattern and to determine one or more turbulence phase correction measurements. The apparatus may include a controller for generating feedback and dynamic tuning signals.

Abrégé

A targeting receiver operates with beam emitters. Each emitter generates coherent beams directed towards a target as a composite beam having an associated signature. For each composite beam, the target reflects a proportion of radiation intensity as a reflected radiation component. A receiver telescope collects target-reflected radiation and directs the radiation to a spatial filter. The reflected radiation includes radiation components, at least some of which are combined as a combined radiation composed of the reflected radiation components. Intensity of the combined radiation indicates the intensity of the composite beams impinging on the target. The spatial filter filters the reflected radiation by selectively passing the combined radiation. Each component of the combined radiation is identifiable by the signature associated with the composite beam corresponding to the component of the combined radiation. In certain embodiments, a distinguishing module is associated with the receiver and distinguishes the components based on the signature.

The invention is a method and apparatus for creating mode division multiplexed channels capable of integration into photonic integrated circuits with direct spatial separation at the receiver end, thus removing the need for a DMUX module or at least significantly simplifying it. This is achieved by using a set of actuators that induce controllable mode mixing in a multi-mode fiber (MMF) at the transmitter in such a way that spatially separated channels are achieved at the receiver. As a result, no DMUX is required and failure of a single channel does not cause total communication link failure as occurs in links implemented with MUX/DMUX.

A potentially interfering node updatable database associated with the MAC, in each node, contains a limited number of unique identification numbers (UNIDs) referring to nodes likely to interfere with the transmission of the node. Typically these UNIDs are one or two hop neighbors. In addition to the actual nodes, the database also contains unique ID numbers of dummy nodes. Practically, the node database does not distinguish between real or dummy nodes. Selecting a certain node to transmit at a certain TS is brought about by a “which node is to transmit in the next TS” (WINIT) function. This function takes into account all the UNIDs available in the UNID databases of the different nodes. When the WINIT selects a specific UNID to be active in the upcoming TS, the relevant MAC element in the respective node, invokes the transmission.

A method for displaying point-of-interest coordinate locations in perspective images and for coordinate-based information transfer between perspective images on different platforms includes providing a shared reference image of a region overlapping the field of view of the perspective view. The perspective view is then correlated with the shared reference image so as to generate a mapping between the two views. This mapping is then used to derive a location of a given coordinate from the shared reference image within the perspective view and the location is indicated in the context of the perspective view on a display.

A method for reducing the effects of background radiation introduced into gaseous plume spectral data obtained by an aerial imaging sensor, includes capturing spectral data of a gaseous plume with its obscured background along a first line of observation and capturing a second image of the previously obscured background along a different line of observation. The parallax shift of the plume enables the visual access needed to capture the radiometric data emanating exclusively from the background. The images are then corresponded on a pixel-by-pixel basis to produce a mapping. An image-processing algorithm is applied to the mapped images to reducing the effects of background radiation and derive information about the content of the plume.

A suspension lug for releasably suspends loads under aircraft. The suspension lug has a lug eye and a threaded base and a rotation mechanism is inserted into the threaded portion. When the suspension lug is threaded into a compatible well in the load and the load is released from the aircraft, the rotation mechanism causes the suspension lug to rotate by ninety degrees from an initial orientation in which the face of the lug eye is pointed in the direction of flight to a final orientation in which the edge of the lug eye is pointed in the direction of flight. The rotation of the lug eye significantly reduces the drag on the load. Also described are methods of manufacturing and using the suspension lug of the invention.

The first pair of plane mirrors reflects a first light incoming ray sequentially to produce first and second reflected light rays within a roughly horizontal plane, the second reflected ray being focused by the objective lens on the focal plane. The second pair of plane mirrors reflects a second incoming ray sequentially to produce third and fourth reflected light rays within a roughly vertical plane, the fourth reflected light ray being focused by the objective lens on the focal plane.

Methods and apparatus for effecting a non-uniformity correction of images of a scene obtained with an array of detector elements are disclosed. A first image of the scene having a first integration period is acquired using the array of detector elements. A second image of the scene having a different integration period is acquired, and a corrected image of the scene is generated by computing a difference of the images. In some embodiments, the first and second images are images of substantially identical scenes. According to some embodiments, the images are infrared images. Optionally, the corrected image is subjected to further correction using pixel dependent correction coefficients, such as gain coefficients. Exemplary image detection elements include but are not limited to InSb detector elements and ternary detector elements, such as InAlSb, MCT (Mercury Cadmium Telluride), and QWIP technology (Quantum Well Infrared Photodiodes). In some embodiments, the detector elements are cooled to a temperature substantially equal to an atmospheric boiling point of liquid nitrogen. Alternatively, the detector elements are cooled to a temperature below an atmospheric boiling point of liquid nitrogen, or any other operating temperature.

Abrégé

A method for iterative derivation of a master image from sampled images of non-identical, at least partially overlapping, regions of a scene. The method includes defining a transformation operator mapping positions within the master image to corresponding positions in the sampled image; a distortion operator simulating a modulation transfer function associated with an imaging sensor from which the sampled image was generated; and a sampling operator for reducing an image from the output resolution to the resolution of the sampled image. For each sampled image the transformation operator, distortion operator and sampling operator are applied to a current master image hypothesis to generate a predicted image A difference image is calculated which has pixel values corresponding to the difference in corresponding pixel values between the sampled image and the predicted image. A back-projection of each of the difference images is performed to generate a correction image for the current master image hypothesis. Finally, the correction images are employed to perform a correction to the current master image hypothesis to generate a new master image hypothesis. The correction to the current master image hypothesis includes combining the correction images by deriving a weighted average of values of corresponding pixels in the correction images. The weight of each pixel in each correction image is calculated as a function of a distance as measured in the sampled image between: a point in the sampled image to which the pixel in the correction image is mapped by the transformation operator, and at least one pixel centroid proximal to that point.
