To provide a method or instrument for manufacturing components for an aerosol generating article improving quality assurance.SOLUTION: A method for manufacturing components of an aerosol generating article 401 including a taggant includes: a step for applying the taggant to a component; a step for detecting an amount of taggants included in the component; a step for determining whether or not the detected amount of the taggant is smaller than a first prescribed amount; and a step for rejecting the component when the detected amount of the taggant is smaller than the first prescribed amount. An instrument for manufacturing components of an aerosol generation article is provided with: a dispenser applying the taggant to the component; a sensor detecting an amount of taggants included in the component; a controller for determining whether or not the detected amount of taggants is smaller than the first prescribed amount; and a rejection system for rejecting components when the detected amount of taggants is smaller than the first prescribed amount.SELECTED DRAWING: Figure 4

The present invention provides spectral code strategies that allow spectral codes to be accurately and consistently deployed in a wide range of substrates and background situations. The present invention uses taggant particles with a multilayer structure that is able to produce a strong, consistent spectral signal that is resistant to background noise effects. The spectral output can be read remotely from a distance using multispectral, particularly hyperspectral, imaging techniques.

A Cascade Spoof Proof Extra-layer Radiant Authentication (CASPER-A) system using spectrally-coded taggants is configured to transmit a multi-wavelength optical interrogation signal to interrogate a nanotag associated with a device. A multi-spectral optical receiver may be configured to receive and decode a response to the interrogation signal that may comprise a multi-spectral emission generated by the nanotag. Processing circuitry may generate data from the decoded response. To authenticate the device associated with the nanotag, the processing circuitry may generate a digital signature. The nanotag may comprise a multi-layered nanocrystal (NC) activated composite material comprising multiple layers configured to generate a multi-spectral emission from optical excitation by the optical interrogation signal. Each layer may comprise a heterogeneously dispersed volume embedded with quantum dots (Qdots). The Qdots may be configured to generate a multi-spectral emission based on an interaction of one or more wavelengths among Qdot emitters by intercoupling.
