A reaction curable resin is irradiated with ultraviolet light having wavelengths of 250 to 380 nm. A screen image of luminance value, which is obtained by extracting only a specific wavelength component of the reflected ultraviolet light, is recorded, and the cured state of an ultraviolet curable resin...http://www.google.fr/patents/US7323693?utm_source=gb-gplus-shareBrevet US7323693 - Apparatus and method for measuring cured state of reaction curable resin
