The potential of non-invasive in situ analytical techniques such as portable Raman, portable X-ray fluorescence, portable optical microscope and fibre optics reflectance spectroscopy has been shown studying painted layers of Renaissance terracotta polychrome sculptures belonging to the statuary of Santo Sepolcro Church in Milan. The results obtained allowed pointing out the contribution of these techniques to the compositional diagnostic, providing complete information, in some cases, better than micro-destructive techniques, on the kind of pigments used on the external painted layers. Moreover, a comparison with the results obtained before the last conservation work (2009) with micro-destructive techniques allowed ascertaining the removal of the external painted layers during the conservation operations.
便携式拉曼、便携式 X 射线荧光、便携式光学显微镜和光纤反射光谱等非侵入式原位分析技术的潜力已经在研究属于米兰圣墓教堂雕像的文艺复兴时期赤陶多色雕塑的涂层中得到了展示。所获得的结果表明，这些技术有助于进行组成诊断，在某些情况下，比微损技术提供了更好的关于外部涂层面上使用的颜料种类的完整信息。此外，与 2009 年（最后一次保护工作之前）用微损技术获得的结果进行比较，证实了在保护过程中去除了外部涂层面。
