Superconducting wire inspection device and inspection method

摘要

An apparatus inspecting a superconducting wire includes: a blue LED (1) emitting light in a direction normal to a front surface (20a) of a superconducting wire (20) to illuminate the front surface (20a); a red LED (2) emitting light in a direction forming an angle with the direction normal to the front surface (20a) of the superconducting wire (20) to illuminate the front surface (20a); a color line sensor (3) mainly receiving light reflected (B1) by the superconducting wire (20), and mainly receiving light diffused (C2) by the superconducting wire (20); and a computer (5) accumulating and outputting a quantity of light received by the color line sensor (3). The apparatus can inspect with high sensitivity whether the superconducting wire has a defect or not.
