    • The invention relates to methods for recording and reading information hidden against a visualisation and can be used for visualising hidden images (marks) which identify an object and protect it against non authorised reproduction (falsification). The inventive method for producing and visualising an optically invisible mark consists in the following: an optically invisible image of the mark is formed on the surface of a studied object by modifying at least one area of said surface. Said image is then visualised. The surface of the studied object (carrying the image) is pre-treated in such a way that it is mirrored prior to forming the optically invisible image of the mark. The modification is accompanied by modifying surface energy of modified areas. The visualisation of the optically invisible image of the mark is performed by creating a metastable medium in the zone of said surface. Using said metastable medium, an optically perceived invisible image of the mark is embodied in the form of the difference of structures formed by particles of the stable phase of the metastable medium on the areas of the surface (of the studied object) having different surface energy. Various variants of the use of metastable mediums and methods for forming the optically invisible image of the mark on the surface of the studied object are also disclosed.
    • 本发明涉及写入和读取从目视观察隐藏的信息的方法,并且可用于可视化识别对象的隐藏图像(标记),这提供了防止未授权再现(伪造)的保护。 光学不可见标记的创建和可视化的方法如下。 在所述物体的表面上,通过修改所述表面的至少一部分形成光学上不可见的标记图像,然后建立所述图像的可视化。 在形成光学不可见标记图像之前,将所述物体的表面(携带所施加的图像)制成镜子。 通过改变正在修改的零件的表面能来实现改性。 此外,光学不可见标记图像的可视化通过在所述物体的所述表面的区域中建立的稳定的环境来实现,通过该环境,获得光学不可见标记的视觉观察图像作为差异 由具有不稳定环境的稳定相的颗粒形成的结构在具有不同表面能的表面(所涉及的物体)的部分上。 提供了关于在光学不可见标记图像的表面上使用元稳定环境以及形成方法的不同变体。

    • An arrangement for shaping and marking a target (S), comprises a processing apparatus (4) which is adapted to mechanically shape the target (S); a marking unit which is adapted to non-mechanically provide markings on the target (S) in a marking area adjacent to the processing apparatus (4); and a supporting unit (3) which supports the marking unit. The supporting unit (3) is slidable between a first position (A) in which the marking unit is aligned with the marking area, for effecting a high-precision marking operation, and a second position (B) in which the marking and supporting units (3) are spaced from the marking area and the processing apparatus (4), to provide immediate and complete access to the marking unit and processing apparatus (4) for maintenance or the like.
    • 用于成形和标记目标(S)的装置包括适于机械地成形目标(S)的处理装置(4)。 标记单元,其适于在与所述处理设备(4)相邻的标记区域中在所述目标(S)上非机械地提供标记; 以及支撑标记单元的支撑单元(3)。 支撑单元(3)可以在其中标记单元与标记区域对准的第一位置(A)和用于进行高精度标记操作的第二位置(B)之间滑动,其中标记和支撑单元 (3)与标记区域和处理装置(4)间隔开,以便提供对标记单元和处理装置(4)的即时和完全访问以进行维护等。
