DIRECTIVE ILLUMINATOR LOCATION DEVICE, USEFUL FOR PANORAMIC DETECTION OF LASER SOURCES

摘要

P DEVICE FOR LOCATING LASERS USING A PASSIVE, DISCREET, SIMPLICALLY EFFICIENT, HIGHLY EFFICIENT SYSTEM. / P P IT HAS A PLURALITY OF C1, ... CN SENSORS TO COVER A FIELD OF OBSERVATION IN STORAGE, THE SENSORS BEING REGULARLY DISTRIBUTED AND GIVEN EACH OF AN OPTICAL RECEIVER OJ AND A BIDIRECTIONAL COUPLER TO AN OPTICAL LINE FB CONNECTED THROUGH ITS ENDS B1, B2 TO A PHOTODETECTOR DEVICE 1, IN ORDER TO PRODUCE TWO OPTICAL PATHS MOVING FROM THE SENSOR TO THE EXTENDED TERMS, THESE PATHS HAVING DIFFERENT LENGTHS AND THE DIFFERENCES OF PATH BEING DISTINCT FOR ALL SENSORS. THE TIME DIFFERENCE OF THE DETECTOR SIGNALS SO PERFORATES THE IDENTIFICATION OF THE SENSOR AND THIS, TO LOCATE ANGULARLY THE INCIDENT RADIATION DETECTED. / P
