摘要
Provided is a stress history recording system capable of recording stress applied to an object to be inspected and capable of checking its light emission history without peeling off the recording means from the object. A light emitting means including a stress luminescent material, recording means containing a photosensitive substance and cumulatively recording the history of the light emission from the light emitting means, a recording means for cumulatively recording the light sensitive material irradiated toward the recording means And filter means for blocking ambient light of a wavelength to be used and transmitting outside light of a predetermined wavelength capable of detecting a degree of change in optical characteristics of the photosensitive material, wherein external light of a predetermined wavelength By irradiating the recording means and observing the reflected light, the history of the stress applied to the object can be confirmed.
