Translation and Introduction:Interpretation on the Mechanism and Application of Intelligent Laser Technologiesin Paper-based Archives Restoration
These are some bottlenecks in traditional restoration of paper archives,either physical means(e.g.scraping)or chemical means(e.g.bleaching)to treat paper archives contaminated with ink or fungi or other stains can cause varying degrees of damage to the fiber structure.In response to these bottlenecks in restoration,this paper reviews the cleaning and restoration of paper archives by laser technology over the past 30 years,summarizing the mechanism of laser action with various types of contaminants,and proposing a new idea of using intelligent laser technology to restore paper archives:Based on the principle of laser"ablation cooling"of paper fibers,the laser can be positioned precisely at the cleaning location by an intelligent control platform.The wavelength,power and polarization of the laser can be flexibly adjusted for different types of contaminants to achieve non-destructive and efficient cleaning and restoration of paper archives.
