Title:
ひずみ計測装置及びひずみ計測方法
Document Type and Number:
Japanese Patent JP7054123
Kind Code:
B2
Abstract:
A strain measuring device (10) comprises: a light source (20), an imaging device (30), and a processing device (40). The light source (20) emits excitation light for exciting a mechanoluminescent body to a predetermined state. The imaging device (30) images light emitted by the mechanoluminescent body. The processing device (40) calculates a strain of the mechanoluminescent body when a force is applied to the mechanoluminescent body, on the basis of a light emission pattern of the mechanoluminescent body when the force is applied to the mechanoluminescent body, and an amount of remaining light of the mechanoluminescent body after being excited to the predetermined state.
