Detection and analysis of jade material using optical coherence tomography

Jade is a type of rare and expensive stone. The current approaches for jade exploration and processing are blindly and wasteful. Capable of performing high resolution, cross-sectional sensing of the internal structure of materials, Optical Coherence Tomography (OCT) could be used to greatly facilitate these jade procedures. By detecting the signal intensity and analysing the internal texture, OCT system can indicate if the jade exists and what the type it could be. It provides a tool to guide the artist in designing and making the jade artworks. It also can be used for discrimination of the fake antique jade wares, as well as anti-counterfeiters on the jade market. In this paper, we present how a Swept-Source OCT system to detect and analysis the internal features of jades. Algorithms for feature extraction and classification are described and experimental results with various unearthed jades are demonstrated.Peer reviewed: YesNRC publication: Ye
