摘要

A deformation distribution is easily measured in a wide range of image acquisition systems. A standard image of the magnetic domains of a sample serving as standard is captured by light radiation using an external standard magnetic field serving as standard, a majority of magnetic domain images are captured in a state in which an external magnetic field is created while it is being modified, a majority of subtraction images obtained by subtracting the default image of magnetic domains from each of the majority of magnetic domain images is captured, a magnetic conversion field,in which a magnetic domain is inverted, is extracted from each of the majority of subtraction images, and a composite image with a majority of magnetization conversion areas is obtained by composing the majority of subtraction images, each of which has the magnetic conversion area.
