Abstract:
1. A stress component measurement method using an irradiation device, a sensor and an information processing unit, comprising: a stress component comparison step that compares a Raman spectrum obtained in a predetermined reference area of a reference specimen to which said given stress component is applied with the stress component, a correlation data production step that conducts the stress component comparison step on each of the multiple reference areas to which a different stress component is applied and that produces correlation data indicating a correlation between the Raman spectrum and the stress component by the use of a multivariate analysis method based on the result of the stress component comparison step, and a stress component calculation step that calculates a stress component applied to a measurement area based on a Raman spectrum obtained in a measurement area of a measurement specimen whose composition is the same as that of the reference specimen and the correlation data.
