      Spectral-Domain Optical Coherence Tomography for the Non-Invasive Investigation of the Pigment Layers of Tang Dynasty Tomb Murals Exhibited in Museums

      Optical coherence tomography (OCT) is a non-invasive subsurface three-dimensional imaging technique based on the Michelson interferometer. Due to the nature of non-invasive detection and high-speed acquisition, OCT is efficient for imaging intact objects to generate a complete overview of their microstructure. This paper presents the investigation of the pigment layer and ground layer of three Tang dynasty tomb murals exhibited in museums with Spectral-domain optical coherence tomography (SD-OCT). The investigation results demonstrated that SD-OCT system can obtain clear images of the subsurface microstructure and preservation status of ancient murals and can precisely locate and measure the location of the mural ...

    2. 1310 nm Source Spectral-Domain Optical Coherence Tomography for Chinese Pigment and Jadeite Research

      1310 nm Source Spectral-Domain Optical Coherence Tomography for Chinese Pigment and Jadeite Research

      Optical Coherence Tomography (OCT) technique is a nondestructive optical detection technology based on low-coherence interferometer and it has become an attractive cultural heritage research method. A 1310 nm source spectral-domain optical coherence tomography (SD-OCT) system based on optical fiber Michelson interferometer and optical spectrum analyzer is proposed and demonstrated for Chinese cultural heritage research. The cross-section OCT images of Chinese pigment samples and jadeite samples can provide a lot of valuable
