AEROSOL-GENERATING SYSTEM AND DEVICE HAVING A WAVEGUIDE ARRANGEMENT FOR AUTHENTICATING AEROSOL-GENERATING ARTICLES

摘要

The present invention relates to an aerosol-generating system comprising an aerosol-generating article (1) comprising an indicium (4) arranged on an outer surface thereof and an aerosol-generating device (2) usable with said article. The aerosol-generating device (2) comprises a cavity (2a), a heater, and an optical reader system. The cavity (2a) has an opening accessible at the outer body part and is configured to receive a consumable article (1) comprising an indicium (4) arranged to said article (1) upon its insertion The optical reader system comprises at least one waveguide (10) that comprises an incoupling (12) and an outcoupling (14) surface, and a detector (30). The waveguide (10) is configured to illuminate said indicium (4) in said cavity (2a) with a light beam (400) and to transmit a light beam (100) provided by said indicium (4) to a detector (30) of said optical reader system The invention is also related to a method for authenticating a consumable article (1).
