Definitions

  • the invention relates to an illumination device comprising an emitter of electromagnetic radiation and an observation system.
  • non-lethal weapons In the field of law enforcement, non-lethal weapons occupy a privileged place because they limit the risk of injury between the protagonists.
  • FR 2886394 describe devices for momentary neutralization of an individual. These devices include a pulse light source coupled to observation means. The synchronization is performed by means of the pulse light source which emits a warning signal to the observation means.
  • the illumination device comprises an emitter 1 of electromagnetic radiation 2 having a wavelength comprised in the visible spectrum and / or in the infrared range.
  • the emitter 1 of electromagnetic radiation 2 may be configured to emit simultaneously in the visible spectrum and in the infrared spectrum or it may be configured to emit either in the visible spectrum or in the infrared range.
  • the emitter 1 of electromagnetic radiation 2 is intended to illuminate a scene and advantageously a target in the illuminated scene.
  • the illumination device also comprises an observation system 3 which is configured to deliver an image representative of the illuminated scene to an observer 4.
  • the observation system 3 is configured to be portable so that the observer 4 be able to carry or transport the observation system 3 in the zone to be illuminated by the transmitter 1.
  • the transmitter 1 is configured to deliver an emission of the electromagnetic radiation 2 by at least one flash or several flashes with a luminous power greater than a threshold generating the dazzling of the target for example an individual or a detection system.
  • the power emitted may be a function of the estimated distance between the light emitter 1 and the target.
  • the estimated distance is between a few meters and about 50 meters.
  • the energy emitted to achieve the incapacitating effect depends on the conditions of use. Indeed, the emitted light energy is stronger if the target is in a bright environment than in a dark environment.
  • the maximum light energy emitted can also be set by means of a standard and / or specific regulation to prevent the eyes of the target from being burned.
  • the transmitter is a laser source.
  • the transmitter is advantageously configured to dazzle a sensor, for example a sensor used for managing the trajectory of a mobile device.
  • the observation system 3 is configured to have a first operating condition and a second operating condition. These two operating conditions are different by modifying the transmission characteristics of the observed scene towards the observer 4.
  • the first operating condition defines a first value or a first set of values of the perceived luminosity in the illuminated environment towards the observer 4.
  • the second operating condition is chosen so as to present a second value or a second set of values. in which less light energy received is transmitted to the observer 4.
  • the second operating condition is chosen so as to transmit less light power than the first operating condition, with equivalent received illumination.
  • the observation system allows the user to observe the illuminated scene according to two different conditions of illumination.
  • the second operating condition may represent an absence of transmission of the received light energy.
  • the observation system 3 can be made by any suitable device that allows an observer 4 to watch a scene, for example a pair of glasses, a camera, an infrared viewing device.
  • transmitter 1 Since transmitter 1 generates electromagnetic radiation by flash, the scene has two very different illumination periods. In a first period, the scene is dimly lit by the transmitter 1 or the scene is not lit by the transmitter 1. The observer 4 can clearly observe the scene because the observation system 3 transmits all or a large part of the indicative radiation. In a second period of illumination, the transmitter 1 generates a very powerful flash. The system observation 3 switches in the second mode of operation to limit the light energy sent to the observer 4 and avoid the glare of the observer 4. Thus, in the second period, the scene is brightly lit and the target is dazzled. The observer 4 is not dazzled because the observation system 3 then transmits little or no radiation.
  • the illumination device further comprises a synchronization circuit 5 which is configured to synchronize the transmitter 1 and the observation system 3 so that the observer 4 is not dazzled during the emission phase of the flashes and that it receives a sufficient amount of light between two flashes.
  • a synchronization circuit 5 which is configured to synchronize the transmitter 1 and the observation system 3 so that the observer 4 is not dazzled during the emission phase of the flashes and that it receives a sufficient amount of light between two flashes.
  • the transmitter 1 Since the transmitter 1 generates flashes of light of short duration and intensity, the human or animal eye is not able to accommodate and an individual subjected to this type of illumination is disoriented.
  • the light emitter 1 emits a first electromagnetic radiation in a specific range of wavelengths, for example at a first wavelength, in order to achieve the synchronization.
  • the first synchronous electromagnetic radiation uses a first wavelength or wavelength range that is different from the wavelength or range of wavelength used by the flashes.
  • the synchronization is performed by a first electromagnetic radiation in the visible range or preferably in the infrared range.
  • the first electromagnetic radiation can also be in a different range, for example radio-frequency.
  • the first electromagnetic radiation is received by the observation system 3.
  • the first electromagnetic radiation can be emitted by the transmitter 1 or not another device.
  • the transmitter 1 comprises a transmission circuit of a first electromagnetic radiation preceding the emission of a dazzling flash of a predetermined distance.
  • the first electromagnetic radiation can be achieved by a longer or shorter emission of a signal.
  • the sent signal can be simple, for example a peak, a square signal or different symbols.
  • the signal may be more complex, for example a plurality of peaks, of square symbol signals having varying durations.
  • the first electromagnetic radiation precedes the dazzling flash of a predetermined time difference.
  • this time difference is fixed.

  • the difference temporal is random and not recorded in the observation system 3.
  • the observation system 3 comprises a receiver of the first electromagnetic radiation.
  • the signal received by the receiver is transmitted to a computer configured to switch the observation system 3 into the second operating condition after said predetermined time difference. If the time difference is fixed, the computer can be a clock that triggers the switchover in the second condition of operation. If the time difference is variable, the variability can be recorded in a memory present in the observation system 3 or it can be described in the first electromagnetic radiation. If the time difference is random, the switchover to the second operating condition at the appropriate time is obtained by recording the time difference inside the signal defined by the first electromagnetic radiation, for example by means of the characteristics of the first electromagnetic radiation. .
  • the receiver and the computer are configured to analyze the synchronization signal and determine the value of the time difference from the characteristics of the first electromagnetic radiation.
  • the characteristics of the first electromagnetic radiation are the wavelength used, the duration of the signal, the signal intensity, its power distribution over time and / or in the emission spectrum. These features can be used alone or in combination.
  • the power or the energy of the signal is not used because it depends strongly on the distance between the emitter of the first radiation and the receiver of this first radiation.
  • the first electromagnetic radiation has a plurality of time-separated or non-time-separated elementary signals, it is possible to use additional characteristics. For example, it is possible to use the difference between two successive elementary signals, the difference in intensity or the sign of the difference in intensity, the wavelengths used. It is also possible to use more conventional coding systems, for example by applying what is achieved in an infrared remote control. Depending on the number of available characteristics, the signal can convey more or less complex data.
  • the first electromagnetic radiation precedes the incapacitating flash by a fixed time difference.
  • the observation system 3 receives the first electromagnetic radiation and a computer triggers the tilting of the observation system 3, after the time difference, in the second mode of operation to contain the flash.
  • two successive incapacitating flashes are preceded by two first electromagnetic radiations and the time differences are different.
  • the time difference between the signal delivered by the first electromagnetic radiation and each incapacitating flash is calculated from information integrated in the signal from the first electromagnetic radiation, for example an amplitude modulation.
