  • Patent number: 8698667
    Abstract: The invention concerns a device for countering and tracking a threat in the form of a homing-head missile, comprising a homing head adapted to receive an incident coherent light beam and to deflect same to produce a transmitted beam. The invention is characterized in that the homing head comprises a biprism including two prisms made of different materials and adapted to divide the transmitted beam into two sub-beams, the refractive index difference between the prisms being adapted to introduce an optical path difference between the two sub-beams which is greater than the coherence length of the incident beam.

  • Patent number: 8432251
    Abstract: A device for capturing biometric characteristics, the device having an optical sensor with a field of view covering a detection zone for detecting optical characteristics, and an electronic control unit that is connected to the sensor in order to control it, the control unit being placed at least in part in the field of view of the sensor and includes a memory containing at least one signature resulting from at least one reference optical characteristic of the control unit as seen by the sensor, and a comparator module for comparing the signature with at least one corresponding signature that results from at least one optical characteristic of the control unit as supplied by the sensor.

  • Patent number: 8340371
    Abstract: A biodetector permits formation of an image of the inner face of the hand or of a finger of a user when the hand or the finger (101) is placed in front of an image-forming device (11), at a defined height (F). The height is adapted such that the biodetection image is sufficiently clear and is indicated to the user by means of a sign (40) projected onto the outer face of the hand or of the finger. Such a biodetector does not require the hand or finger to be applied to a support surface, and it permits intuitive and rapid use of the biodetector.
