<P>PROBLEM TO BE SOLVED: To highly accurately measure a residual stress of a measuring object despite mounting accuracy of an imaging plate. <P>SOLUTION: A controller CT irradiates a reference object BOB whose residual stress is 0 and a measuring object with X rays from an X-ray emitter 13 to capture diffraction rings of the reference object BOB and the measuring object OB on an imaging plate 28. The controller CT detects the shapes of both the captured diffraction rings respectively, calibrates the shape of the diffraction ring of the measuring object OB using the shape of the diffraction ring of the reference object BOB, and reduces the influence of a mounting error of the imaging plate 28 with respect to a table 27. <P>COPYRIGHT: (C)2013,JPO&INPIT |
