ABSTRACT Conservation investigation often includes substantial technical analysis, and digital tools now permit visitor engagement with this content in museum galleries. Reflectance Transformation Imaging (RTI) and 3D laser scanning were integral parts of a recent technical study of gilt metalwork performed on an early 19th-c. French table centerpiece at Cooper Hewitt, Smithsonian Design Museum (CHSDM). RTI permitted interactive viewing of surface textures to show toolmarks evident from manufacturing. 3D laser scanning allowed comparison of two closely related figures, one of which is believed to be a surmoulage (replacement cast) made from the other. While historical gilt metalwork has been the focus of conservation research for many decades, these digital tools both support innovative scholarship and provide an entry point for new audiences. CHSDM adapted these digital files to create an in-gallery interactive didactic, allowing visitors to learn more about the conservation project through self-guided content. Given an increasingly digital-savvy museum public, the exhibition didactic allowed the conservators to interface with non-specialists and created a precedent for similar collaboration.

与公众分享保护成像研究

摘要保护性调查通常包括大量的技术分析，并且数字工具现在允许访问者在博物馆画廊中使用此内容。反射率转换成像（RTI）和3D激光扫描是在19世纪早期进行的金边金属制品最新技术研究的组成部分。史密森尼设计博物馆（CHSDM），库珀·休伊特（Cooper Hewitt）的法国餐桌核心。RTI允许交互查看表面纹理，以显示制造过程中显而易见的工具标记。3D激光扫描可以比较两个紧密相关的图形，其中一个被认为是由另一个图形制作的替代品。尽管数十年来历史悠久的镀金金属制品一直是保护研究的重点，但这些数字工具既支持创新奖学金，又为新读者提供了切入点。CHSDM修改了这些数字文件，以创建一个画廊内互动教学法，使访问者可以通过自我指导的内容来了解​​有关保护项目的更多信息。鉴于越来越多的精通数字博物馆的公众，展览的教学法使保管者可以与非专家互动，并为类似的合作开创了先例。
