Development of a multi-wavelength laser cleaning system for artwork conservation

该项目将开发一种用于艺术品保护的新型激光清洗系统。激光清洗是一种极其可控和敏感的方法，可以清除艺术品和其他遗产物品上难看的和潜在的破坏性污垢、漆层、腐蚀层和其他不需要的表面附着物。绝大多数激光清洗系统提供波长为1064 nm的激光辐射，非常适合各种材料的高质量清洗，包括：大理石、石灰石、砂岩、陶土和石膏。该项目将专注于开发与Lynton激光紧凑型菲尼克斯系统兼容的激光机头，以提供2940 nm的激光辐射，用于处理使用1064 nm的激光辐射或通过更传统的清洁方法无法令人满意地清洁的人工制品。这些层包括来自绘画的旧变色清漆层，来自石刻的有机物质，以及来自考古金属文物的腐蚀层。新型混合式1064/2940 nm激光清洗系统的开发将是世界上第一个，使林顿激光公司的紧凑型菲尼克斯系统成为目前最多功能的激光清洗系统。

This project will develop a novel laser cleaning system for artwork conservation. Lasercleaning is an extremely controllable and sensitive method of removing unsightly andpotentially damaging pollution encrustations, paint layers, corrosion layers and otherunwanted surface accretions from works of art and other heritage objects. The vast majority oflaser cleaning systems deliver laser radiation at a wavelength of 1064nm, which is ideal forhigh quality cleaning of a wide range of materials, including: marble, limestone, sandstone,terracotta and plaster. This project will focus on developing a laser handpiece, compatiblewith Lynton Lasers Compact Phoenix system, to deliver laser radiation at 2940nm for treatingartefacts which cannot be cleaned satisfactorily using laser radiation at 1064nm or by moretraditional methods of cleaning. Such layers include old discoloured varnish layers frompaintings, organic substances from stone carvings and corrosion layers from archaeologicalmetal artefacts. The development of a novel hybrid 1064/2940nm laser cleaning system wouldbe a world first, making Lynton Lasers’ Compact Phoenix system the most versatile lasercleaning system currently available for conservation.
