  • Method and device for detecting an object that can retroreflect light
    Patent number: 7858920
    Abstract: According to the invention, two simultaneous images with different wavelengths (?1, ?2) are formed in synchronism with each illuminance laser pulse, one of the Images corresponding to the wavelength (?1) of the laser pulses, and the difference between the two images is generated.
    Type: Grant
    Filed: November 22, 2007
    Date of Patent: December 28, 2010
    Assignee: Campagnie Industielle des Lasers Cilas
    Inventors: Jean-Louis Duvent, Jean Yves Thomas, Pierre Morin, Bernard Robic
  • Method and Dual Laser Device for Detecting Magnifying Optical Systems
    Publication number: 20100128992
    Abstract: The invention comprises illuminating a scene where said magnifying optical system (OP) may occur with at least a first and a second pulses respectively generated by first and second laser transmitters (E1, E2). The first laser transmitter (E1) and a detector of the scene thus illuminated (D) are adjacent, while the second laser transmitter (E2) is remote from said detector (D) transversally to the direction (d) of said scene.
    Type: Application

  • Method and Single Laser Device for Detecting Magnifying Optical Systems
    Publication number: 20100067744
    Abstract: The invention comprises illuminating a scene where said magnifying optical system (OP) may occur with at least one pulse generated by first laser transmitter (E). The laser transmitter (E) and a first detector of the scene thus illuminated (D1) are adjacent, while a second detector (D2) is remote from said transmitter (E) transversally to the direction (d) of said scene.
