    摘要： The invention pertains to the use of sophisticated chemical formulation and spectroscopic design methods to select taggants compatible with the 3D print medium that are easily detected spectroscopically but otherwise compatible with the product, structural integrity and stability, and aesthetics. A spectral pattern employs a different chemical or combination of chemicals to alter the formulation of all or some portion of the printed object so that its authenticity can be monitored later using a spectrometer.

    摘要： A box 14 having a body 13 is used with a transparent flexible bag containing a liquid such as an IV bag. First and second faces 12 are positioned relative to each other. The faces each have therewithin an end or fiber optic port 11 of a respective light path. A light source is optically coupled with the light path of the first face and a spectrometer is optically coupled with the light path of the second face. The light paths are coaxial and are disposed so that the transparent flexible bag is positionable therebetween. The spectrometer is disposed to detect an anomaly in the liquid within the transparent flexible bag, and to annunciate the anomaly to a human user. The box defines a reproducible light path length through the liquid. A caliper 29 having a body 22 may be used in spectrometric analysis of a transparent tube containing a liquid such as a syringe or an IV line. The caliper has finger pads 27 which permit opening the spring-loaded caliper as needed. Rivets 25 provide a pivoting action relative to a pivot structure 21 which can also serve as a distance gauge. Compression spring 24 urges the caliper jaws together at lens locations 26. Lens locations 26 are optically coupled with internal fiber optic lines 28, and thence to external fiber optic connectors 23. A light source is optically coupled with one of the connectors 23 and a spectrometer is optically coupled with the other of the connectors 23.
