技術摘要-中文 | 本發明係關於一種利用奈米金屬光柵之防偽識別方法及其系統,係在具防偽需求的物品上設一奈米級金屬米柵,作為防偽用途;作識別時係令一光源以一角度入射奈米金屬光柵,利用奈米金屬光柵對於入射光僅有反射光與穿透光之特性,在奈米金屬光柵特定的相對位置上觀察其是否產生反射光及穿透光,以作為真偽識別;又奈米金屬光柵可先經偏極處理,而對不同偏極方向的入射光分別產生反射或穿透,遂可在奈米金屬光柵特定的相對位置上觀察是否出現偏極光,以識別其真偽;另識別時可進一步旋轉奈米金屬光柵,並觀察其出現反射光及穿透光的位置及強度是否改變,以作為真偽識別。The present invention relates to an anti-counterfeit method using a nano metal grating. An object intended to be recognized is formed with the nano metal grating. During the recognition process, an incidental light beam is applied on the metal grating along a particular incident angle. In response to the incidental light beam, the metal grating has its specific optical incidence and reflection characteristics. Therefore, the object can be identified to determine whether it is a counterfeit object by observing the light beam passing through and reflected from the metal grating. Further, the incident light beam can be polarized to generate the polarized light beam and then applied to the metal grating. Also, the recognition for the object is accomplished by observing the polarized light beam passing through and reflected from the metal grating. Moreover, the recognition can be accomplished by rotating the metal grating, thus the positions and the intensity of the light beam passing through and reflected from the metal grating will accordingly be changed, thereby identifying the object. |
