procedure for the identification of legitimate products, identifikationssiegel and identifikationsvorrichtung

摘要

a fourier transformationshologrammbild on a sheet by means of a label is generated. the picture is a pru00e4geplatte decrease by a fourier transformationshologrammbild - zwischenoriginalplatte and forms of plastic on the pru00e4geplatte generated. the formed image on the sheet by means of a identifikationsvorrichtung reconstructed.the identifikationsvorrichtung contains a laser aussendendes device and a screen for receiving a reflected laser beam. the laser beam is perpendicular to the sheet by the laser emitting device. the laser beam is reflected by the leaf surface and the screen are received and the image on the sheet on the screen is reconstructed.at the same time, it is possible, due to an opening in the housing to check whether the laser beam reaches the leaf.
