摘要
A residual thermal strain distribution measurement method of measuring a residual thermal strain distribution as residual thermal deformation in a sample generated under application of a thermal load, comprises recording images of a periodic pattern present on the surface of the sample by an image recording unit at a first temperature and a sample formation temperature at which the sample is formed, generating moire fringes based on each recorded image of the periodic pattern, calculating a phase of the moire fringes for the sample at the first temperature, calculating a phase of the moire fringes for the sample at the sample formation temperature, acquiring a phase difference of the moire fringes at the sample formation temperature with respect to the first temperature, and calculating a residual thermal strain of the sample at the first temperature with respect to the sample formation temperature based on the acquired phase difference.
