Feature Of The Week 7/4/10: Researchers at the National Research Council Canada have been very active in pushing the frontier of Optical Coherence Tomography across a wide range of technologies and applications. Recently Dr. Shoude Change et al published on a novel non-destructive evaluation application of OCT entitled "Jade Detection and Analysis Based on Optical Coherence Tomography Images". With a depth resolution of 4 mm in jade, and penetration range of 5 mm in jade, Swept-Source OCT could be used as a new powerful instrument to generate 3D volume data of jade, which is important for applications in jade industry and artwork, particularly for jade detection and classification, counterfeit recognition, and guided artistic carving.
