Paintings have high cultural and commercial value, so that needs to be preserved. Many techniques have been attempted to analyze properties of paintings, including X-ray analysis and optical coherence tomography (OCT) methods, and enable conservation of paintings from forgeries. In this paper, we suggest a simple and accurate optical analysis system to protect them from counterfeit which is comprised of fiber optics reflectance spectroscopy (FORS) and line laser-based topographic analysis. The system is designed to fully cover the whole area of paintings regardless of its size for the accurate analysis. For additional assessments, a line laser-based high resolved OCT was utilized. Some forgeries were created by the experts from the three different styles of genuine paintings for the experiments. After measuring surface properties of paintings, we could observe the results from the genuine works and the forgeries have the distinctive characteristics. The forgeries could be distinguished maximally 76.5% with obtained RGB spectra by FORS and 100% by topographic analysis. Through the several executions, the reliability of the system was confirmed. We could verify that the measurement system is worthwhile for the conservation of the valuable paintings. To store the surface information of the paintings in micron scale, we created a numerical database. Consequently, we secured the databases of three different famous Korean paintings for accurate authenticity.
绘画作品具有很高的文化和商业价值，因此需要加以保护。人们尝试了许多技术来分析绘画作品的特性，包括X射线分析和光学相干断层扫描（OCT）方法，以实现对绘画作品的真伪鉴别及保护。在本文中，我们提出了一种简单且准确的光学分析系统，用于保护绘画作品不被伪造，该系统由光纤反射光谱（FORS）和基于线激光的地形分析组成。该系统旨在无论绘画作品大小，都能全面覆盖其整个区域以进行准确分析。为了进行额外评估，还使用了基于线激光的高分辨率OCT。专家们根据三种不同风格的真品绘画创作了一些赝品用于实验。在测量了绘画作品的表面特性后，我们可以观察到真品和赝品具有明显不同的特征。通过FORS获得的RGB光谱，赝品的鉴别准确率最高可达76.5%，通过地形分析则为100%。通过多次实验，该系统的可靠性得到了证实。我们可以验证该测量系统对于保护珍贵绘画作品是值得的。为了以微米级存储绘画作品的表面信息，我们创建了一个数字数据库。因此，我们获取了三件不同的韩国著名绘画作品的数据库，以确保鉴定的准确性。
