    Abstract: Systems and methods are provided, which use at least two coherent light sources with known phase relations between them, which are configured to illuminate a target with at least two corresponding spots, an optical unit comprising a mask and configured to focus, onto a sensor, interfered scattered illumination from the spots of the target, passing through the mask, to yield a signal, at least one shifter configured to shift a frequency of at least one of the coherent light sources to provide a carrier frequency in the signal, and a processing unit configured to derive a vibration frequency of the target from the sensor signal with respect to the carrier frequency. The vibration frequency of the target is separated from the carrier frequency and speckle disturbances may be attenuated or avoided.

    Abstract: Systems and methods are provided for vibrations detection in a scene. Systems comprise at least one coherent light source configured to illuminate the scene, an optical unit configured to focus scattered light from the scene onto a pixelated detector, the detector configured to provide pixel intensity signals, and a processing unit configured to analyze the pixel intensity signals over the pixels of the detector to derive a vibration spectrum of elements in the scene that correspond to the pixels. The signal modulation at each pixel may be used to indicate the vibrations of the scene element(s) that corresponds to the pixel(s). Vibration information concerning the scene may be used to direct other methods of vibration measurements, such as speckle interferometry, according to derived vibration images of the scene.

    Abstract: A system for determining the authenticity of an object including a reference-image acquisition module for acquiring a reference-image. The reference-image acquisition module includes a light-source, an imager including an imaging-sensor, and a database coupled with the imager for storing the reference-image. The light-source directs circumferential-light toward an authentication-region on the object. The circumferential-light is at least one of collimated and telecentric. The circumferential-light impinges on the authentication-region from a plurality of different azimuthal directions and at a predetermined oblique angle relative to the normal of a plane defined by said object. A portion of the circumferential-light is reflected from the authentication-region toward a specular reflection region and another portion is scattered from the authentication-region. The imager is focused on the authentication-region and acquires a reference-image. The reference-image is a focused image of the scattered light. The reference-image includes image features related to surface features scattering phenomena of the authentication-region.

    Abstract: Navigation systems and methods are provided. A classifier is configured to transform a received image of a terrain into a classified image in which patches of pixels from the received image are represented as being in one of a specified number of material classes, each associated with respective terrain parameters. A physical traversability module is configured to determine, for the material parameters, a terrain topography and given vehicle parameters, a degree of traversability of the vehicle through the terrain as represented by the received image, to yield a traversability map. A routing module is configured to derive traversability measure(s) for route(s) through the classified image and with respect to the traversability map, between a given origin and a given destination or within a region with respect to a user-defined mission. A graphical user interface is configured to display the route(s) according to the traversability measure(s).

    Abstract: A mobile ad-hoc communications network with multi-interface dynamic routing includes multiple mobile nodes with mobile wireless communication and multiple mobile nodes with mobile wireless communication and satellite communication. At least some of the mobile nodes with mobile wireless communication are dynamically-switched between operating as an ordinary node or as a backbone node. At least some of the mobile nodes with mobile wireless communication and satellite communication are dynamically-switched between operating as an ordinary node or as a backbone node. All of the mobile nodes communicate over a dynamically-formed ordinary communication link. Mobile nodes operating as backbone nodes additionally communicate over a dynamically-formed backbone link. Data is routed in the network by an ad-hoc multi-interface dynamic routing which routes data between the mobile nodes by mobile wireless communication and by satellite communication in accordance with respective communication capabilities of the mobile nodes, so as to incorporate satellite communications into the network.

    Abstract: An air CO2 filtration assembly or system is provided that includes CO2 filters or traps designed and configured with a limited, but high capacity, volume to maximize filtration/absorption of CO2 from an air stream supplied to an alkaline fuel cell to thereby minimize the CO2 level in the air stream fed into the fuel cell cathode. The CO2 filters or traps include at least one thermally regenerative CO2 chemical filter or trap arranged in a tandem configuration with a strongly bonding CO2 chemical filter or trap. The combination of the two types of filters or traps sequentially filter/absorb CO2 from the air stream and reduce the level of CO2 in the air stream fed into the cathode. The air CO2 filtration assembly or system may be used in conjunction with electrochemical purging of the alkaline fuel cell that enables removal of CO2 from the fuel cell by anodic decomposition of accumulated carbonate ions in the fuel cell anode and release of CO2 through the anode exhaust stream.

    Abstract: Method and system for coordinating between separate image sensors imaging a mutual area of interest at different imaging perspectives. A target point is designated on a first image acquired by a first image sensor. Feature points are defined and characterized on the first image and transmitted over a data communication link to a second image sensor. The target point is identified in a second image acquired by the second image sensor using an iterative convergence operation. The first iteration involves locating feature points in the second image corresponding to the defined first image feature points. Subsequent iterations involve locating feature points in a subregion of the second image corresponding to decreasing subsets of first image feature points, the subregion defined by the feature point cluster located in the previous iteration. When a termination condition is reached, the remaining cluster of located feature points is established to represent the target point.
