Abstract:
In the field of engineering, surface metrology is a valuable tool codified by international standards that enables the quantitative study of small-scale surface features. However, it is not recognized as a resource in the field of cultural heritage. Motivated by this fact, in this work, we demonstrate the use and the usefulness of surface metrology based on scanning conoscopic holography for monitoring treatments on the Venetian masterpiece by Tintoretto St. Martial in Glory with the Saints Peter and Paul. We carried out in situ and in-process monitoring of the painting microtexture during an experimental, innovative laser-chemical treatment, and we performed a statistical analysis based on ISO areal field parameters. A wide and in-band roughness analysis through the complementary use of amplitude, spatial, and hybrid parameters confirmed the noninvasive nature of the whole treatment on the painting surface topography, giving us the chance to review and critically discuss the use of these parameters in a real case in heritage science.

在工程领域,表面计量是一个有价值的工具编码的国际标准,使小尺度的表面特征的定量研究。然而,它不被认为是文化遗产领域的资源。出于这一事实,在这项工作中,我们证明了基于扫描锥镜全息术的表面计量学的用途和实用性,用于监测TintorettoSt.Martial在圣徒彼得和保罗的荣耀中对威尼斯杰作的治疗。我们在实验过程中对绘画微观纹理进行了原位和过程中的监测,创新的激光化学处理,并且我们基于ISO区域场参数进行了统计分析。通过振幅的互补使用进行宽带内粗糙度分析,空间,和混合参数证实了整个处理对绘画表面形貌的非侵入性,让我们有机会在遗产科学的真实案例中回顾和批判性地讨论这些参数的使用。
