Abstract:
1. An apparatus inspecting a superconducting wire, comprising: an illumination unit emitting light to illuminate a superconducting wire; a photoreceptive unit receiving light from said superconducting wire; and an output unit accumulating and outputting a signal representing a quantity of light received by said photoreceptive unit; further comprising a laser displacement sensor including a laser light illumination unit emitting a laser beam of light to illuminate said superconducting wire while moving relative to said superconducting wire in a longitudinal direction of said superconducting wire, a laser light reception unit receiving a laser beam of light reflected by said superconducting wire, and an output unit associated with said laser displacement sensor and outputting information on displacement of said superconducting wire as based on at which position said laser light reception unit receives light.
