    Contactless mapping of ceramic green density using optical coherence tomography

    We propose a contactless method for mapping the density distribution of green ceramics using optical coherence tomography (OCT). A correlation was found between the OCT signal and density of green alumina tablets. Using this relationship, proof-of-concept mapping of model samples produced reasonable results, suggesting that high-speed, contactless mapping of the ceramic green density with micrometer-scale resolution is possible, owing to the unique features of OCT. This technique may contribute to more efficient and eco-friendly ceramics production.
