Abstract

Abstract Translated from French Ce dispositif comporte un laser continu (1) infrarouge dirigé vers la caméra (25), un récépteur (10) des signaux infrarouges renvoyés par la caméra, un circuit de traitement (23) de ces signaux, capable de déterminer un temps de retard, un circuit de retard (22) délivrant des signaux électriques retardés dudit temps de retard par rapport à la réception des signaux infrarouge, et un laser pulsé (16) envoyant vers la caméra (25) des impulsions laser respectivement à la réception des signaux retardés. Application à la détection d'une caméra infrarouge adverse disposée sur un char de combat. This device comprises a continuous infrared laser (1) directed towards the camera (25), a receiver (10) for the infrared signals returned by the camera, a processing circuit (23) for these signals, capable of determining a delay time, a delay circuit (22) delivering electrical signals delayed by said delay time relative to the reception of infrared signals, and a pulsed laser (16) sending laser pulses to the camera (25) respectively upon receipt of the delayed signals. Application to the detection of an opposing infrared camera placed on a battle tank.
