摘要

Provided is a stress history recording system with which stress applied to a test object can be recorded, and with which light emission history can be checked without peeling off a recording means from the object. This system comprises: a light emitting means including a mechanoluminescent material; a recording means that includes a photosensitive substance, and that cumulatively records the history of light emission from the light emitting means; and a filter means that blocks, among external light projected toward the recording means, external light having a wavelength that photosensitizes the photosensitive substance, and that transmits external light having a predetermined wavelength with which it is possible to detect the degree of change in optical characteristics in the photosensitive substance. By irradiating, via the filter means, the recording means with external light having said predetermined wavelength and observing the light reflected therefrom, it is possible to check the history of stress applied to an object.
