Abstract
Una apparecchiatura opto elettronica e metodo per il controllo automatico di autenticità di documenti e oggetti mediante ologrammi costituita da un illuminatore per illuminare un ologramma, non visibile con la luce normale, da una interfaccia meccanica che determina e fissa nello spazio la posizione dell'oggetto stesso e dell'ologramma su di esso applicato, da una superficie riflettente disposta in modo da riprodurre una immagine relativa all'ologramma illuminato e da un dispositivo di lettura per rilevare l'immagine, il dispositivo di lettura essendo collegato ad un visualizzatore per visualizzare dati rilevati relativi all'immagine, in uscita del dispositivo di lettura essendo prevista una linea dati esterna.An optoelectronic device and method for the automatic control of authenticity of documents and objects by means of holograms consisting of an illuminator to illuminate a hologram, not visible with normal light, by a mechanical interface which determines and fixes the position of the object itself in space and of the hologram applied to it, from a reflective surface arranged so as to reproduce an image relating to the illuminated hologram and from a reading device to detect the image, the reading device being connected to a display to display detected data relating to the image, an external data line is provided at the output of the reading device.
