    Application of a long-rangesweptsource optical coherence tomography-based scheme for dimensional characterization of multilayer transparent objects

    This work presents the use of a recently develop edinter ferometric system based on the swept source optical coherence tomography (SS-OCT) technique, which allows the characterization of transparent and semitransparent multilayer systems employing a tunablefiber-optic laser with a coherence length suitable for achieving long-deeprange imaging (<10  cm). The inclusion of fiber Bragggratings in the system allow sit to perform a self-calibration in each sweep of the light source. Measurements carried out on cuvettes, ampoules, small bottles, and glass containers used in the pharmaceutic al industry are presented. The thicknesses of the walls and the distance between them were determined. Transparent and semitransparent objects of a multilayer type of different thicknesses were also measured. The configuration presented allow sextension of the measurement range obtainable with the usual OCT systems, demonstrating the potentiality of the proposed scheme to carry out quality control in industrial applications.
