  • the area (A3) is checked, and (step S130), if the first area (A2) is smaller than the second area (A3), the control unit 310 controls the driving unit to The first reflector 215 and the second reflector 235 are controlled to rotate counterclockwise. (Step S150)
  • the security scanner 10 controls the driving unit by the control unit 310 even when the inspection object P is not accurately located within the guide unit 130 of the case unit 100. 1
  • the security scanner 10 controls the driving unit by the control unit 310 even when the inspection object P is not accurately located within the guide unit 130 of the case unit 100. 1
  • the reflector 215 and the second reflector 235 By rotating the reflector 215 and the second reflector 235 at a predetermined angle, complete image data for a specific part of the test object P is acquired, and the examination table is detected through the acquired image data.
  • Dangerous substances (D) hidden in specific parts of the upper body (P) can be detected more closely, making it possible to prevent accidents such as terrorism caused by dangerous substances (D).

Abstract

Un scanner de sécurité destiné à détecter des marchandises dangereuses dissimulées, selon un mode de réalisation de la présente invention, concerne un scanner de sécurité destiné à détecter un article dangereux dissimulé par un objet à cribler par irradiation de l'objet à cribler avec des ondes électromagnétiques d'ondes millimétriques ou térahertz, comprenant : une partie de boîtier formant un espace interne et permettant à l'objet à cribler d'être positionné sur une surface; un module d'inspection disposé dans l'espace interne destiné à appliquer les ondes électromagnétiques à l'objet à cribler, recevoir les ondes électromagnétiques réfléchies à partir de l'objet à cribler, et générer des données d'image sur la base des ondes électromagnétiques réfléchies; et un serveur qui affiche des marchandises dangereuses dissimulées par l'objet à cribler sur la base des données d'image reçues du module d'inspection.
