<P>PROBLEM TO BE SOLVED: To provide a method for measuring a current flowing through a fastener in a structure similar to an actual structure. <P>SOLUTION: A current measurement method includes: a step (a) in which an optical fiber is wound around the periphery of the fastener; a step (b) in which a first linearly polarized light is made incident from the other end of the optical fiber; a step (c) in which the incident first linearly polarized light is reflected at one end and a second linearly polarized light emitted from the other end of the optical fiber is detected; and a step (d) in which a current I is specified based on a rotational angle of a polarization plane of the second linearly polarized light with respect to the first linearly polarized light. <P>COPYRIGHT: (C)2012,JPO&INPIT |
