智能激光技术在纸质档案修复中的机理研究与应用译介

Translation and Introduction:Interpretation on the Mechanism and Application of Intelligent Laser Technologies in Paper-based Archives Restoration

传统纸质档案修复存在一些技术瓶颈,无论利用物理方法(诸如刀刮)还是化学方法(诸如漂白)处理纸质档案的墨渍、霉菌及其他污染类型,均会对纸张纤维结构造成不同程度的损伤。针对上述技术瓶颈,本文综述了近三十年来激光技术用于纸质档案清洗修复的实例,分析了激光清洗多种类型污染物的作用机制,提出利用智能激光技术修复纸质档案的新思路,即基于激光作用于纸张纤维的“烧蚀冷却”原理,利用智能控制平台对拟清洗位置精准定位,在此基础上针对不同污染物灵活调控激光器的波长、功率、偏振等参数,最终实现纸张纤维无损高效清洗的修复目标。

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 f lexibly adjusted for different types of contaminants to achieve non-destructive and efficient cleaning and restoration of paper archives.
