title: A study on the protection to relics and the related problems with diffuse reflectance spectroscopy.
abstract: The application of diffuse reflectance spectroscopy to relic protection is studied by using a self-made fiber optics reflectance spectrophotometer. The major work done includes: (1) the composition of pigment on colored relics and its changes are identified; (2) the change on metal surface is monitored; (3) the reflectance spectrum characteristics of relic protection materials are studied. The results tell that diffuse reflectance spectroscopy is a new protection technique, characterized by its quickness and non-destructiveness to the relic.
