SAMPLE MEASUREMENT METHOD OF USED MAGNETISM ARRAY SENSOR AND RECOGNITION EQUIPMENT TO SENSING FOR FORGERY WHETHER OR NOT OF MAGNETISM ARRAY SENSOR

摘要

PURPOSE: An apparatus for recognizing forgery using a magnetic array sensor and a method for measuring a specimen using the same are provided to easily verify the forgery of the specimen by accurately measuring soft magnetic substance. CONSTITUTION: A specimen(50) includes a soft magnetic substance and a hard magnetic substance. A first magnetic sensor(31) measures the soft magnetic substance. A second magnetic sensor(32) includes magnet and magnetizes the soft magnetic substance. The second magnetic sensor measures both the soft magnetic substance and the hard magnetic substance. A magnetic array sensor is composed of the first magnetic sensor and the second magnetic sensor.
