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 . 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，表面计量学是一种由国际标准编纂的重要工具，可用于对小规模表面特征进行定量研究。然而，它在文化遗产领域并未被视为一种资源。基于这一事实，在本研究中，我们展示了基于扫描锥光全息术的表面计量学在监测丁托列托的威尼斯杰作的修复处理中的应用及实用性。我们在一种实验性的创新激光化学处理过程中对这幅画作的微观纹理进行了现场和过程监测，并基于ISO面域参数进行了统计分析。通过互补使用幅度、空间和混合参数进行的广泛且带内粗糙度分析证实了整个处理过程对画作表面形貌的非侵入性，这使我们有机会在遗产科学的实际案例中审视并批判性地讨论这些参数的使用。
