  • Patent number: 10234255
    Abstract: A fuze for detecting an obstacle in proximity, an obstacle in proximity defined as being an obstacle exhibiting a minimum distance from the fuze, wherein the fuze comprises at least: an emission device emitting a light beam directed forward of the fuze; a reception device detecting the luminous fluxes in a cone directed forward of the fuze, the light beam and the cone having relative orientations such that they cross one another; a detection volume being the volume where the light beam crosses the cone so that when an obstacle is in the detection volume, the light emitted by the emission device is backscattered toward the detection device, an obstacle in proximity being detected by detecting the maximum of backscattered power, the reception cone is centered on the axis of the fuze.

  • Patent number: 9784823
    Abstract: A panoramic device for detection of laser pulses is provided, sensitive to at least two wavelengths and including a plurality of optical channels and a set of linear sensor arrays, each linear sensor array including a photosensitive area. Each optical channel includes at least two linear sensor arrays, the respective photosensitive areas of said at least two linear sensor arrays being non-contiguous, so that said at least two linear sensor arrays of each optical channel observe non-contiguous angular fields. Moreover, the optical channels are optically juxtaposed to obtain a continuous angular field of surveillance.

  • Patent number: 9495595
    Abstract: A method for detecting a stream of electromagnetic pulses emitted, according to a predefined occurrence law, in a scene observed using a detection system comprising a matrix detector and a processing unit for processing signals comprising the electromagnetic pulses. The method includes the following steps: acquiring and transmitting the signals from the matrix detector to the processing unit, and for each pixel of the detector calculating a subtraction signal between two signals acquired during two consecutive time windows of the same length, calculating a signal for accumulating the subtraction signals spaced apart in time by an interval defined by the predefined occurrence law, and thresholding the accumulation signal, the pulse being detected if the accumulation signal is greater than a predetermined threshold for at least one pixel, and locating the pulse detected in the observed scene from the coordinates of the pixel including the detected pulse.
