Title:
MAGNETIC FIELD MEASURING SYSTEM, MAGNETIC FIELD MEASURING METHOD AND PROGRAM
Document Type and Number:
Japanese Patent JP2018077052
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a magnetic field measuring system or the like which allows for: detecting an intensity change of a magnetic field of an object with high sensitivity even if the intensity change of the magnetic field is minute; and consequently, accurately obtaining an operation result obtained by operation processing, such as detecting a deterioration state or abnormality of the object using intensity of the magnetic field.SOLUTION: A magnetic field measuring system 1 has a configuration of: applying a voltage of a predetermined value to a magnetic sensor 210 consisting of a TMR sensor; converting a current value generated at the magnetic sensor 210 by scanning an object 201 into a voltage value by linearly and logarithmically amplifying the current value at a logarithmic amplifier 4; and performing imaging or other processing of intensity of a magnetic field by performing predetermined operation processing using the converted voltage.SELECTED DRAWING: Figure 1
