    • The invention relates to a device (20) and a method for making visible security elements present in an object (4) and comprising at least one photoluminescent segment which is characterized by linearly polarized photoluminescence and/or linearly polarized absorption. According to the invention, a good contrast is achieved with few interfering signals, by arranging at least one light source (1) and at least one polarization filter (2) in such a way that the light (24) from the light source (1) is linearly polarized (23) by means of the polarization filter (2) and hits the object (4) or the photoluminescent segments in said object, and photoluminescent light (25) from the segments can be observed through another and/or the same polarization filter (2).
    • 本发明涉及一种用于制造存在于物体(4)中的可见安全元件的装置(20)和方法,该装置包括至少一个以线偏振光致发光和/或线偏振吸收为特征的光致发光段。 根据本发明,通过以如下方式配置至少一个光源(1)和至少一个偏振滤光器(2),使来自光源(1)的光(24)的方式通过少量干扰信号实现良好的对比度 )通过偏振滤光器(2)被线偏振(23)并且击中物体(4)或所述物体中的光致发光段,并且可以通过另一个和/或相同的观察到来自该段的光致发光(25) 偏振滤光片(2)。

    • The invention relates to a device (20) for making security elements visible, which are provided in an object (8) and have at least one photoluminescent segment that is characterized by having a linearly polarized absorption. The aim of the invention is to obtain a device of this type that has a particularly simple and compact design. To this end, at least one UV light source, which is provided in the form of a UV diode (18), and at least one polarization filter (4) are arranged so that the light of the light source (18) is linearly polarized (12) by the polarization filter (4) and, in a dark space (17), strikes the object (8) with respect to the photoluminescent segments provided therein, and photoluminescent light (16) in the visible range emitted by the segment can be observed through an observation opening (10).
    • 本发明涉及一种用于使安全元件可见的装置(20),其被提供在物体(8)中并且具有至少一个特征在于具有线偏振吸收的光致发光段。 本发明的目的是获得具有特别简单和紧凑设计的这种类型的装置。 为此,设置以UV二极管(18)的形式提供的至少一个UV光源和至少一个偏振滤光器(4),使得光源(18)的光线性地被线性偏振 (12),并且在暗空间(17)中,相对于设置在其中的光致发光片撞击物体(8),并且由该片段发射的可见光范围内的光致发光(16)可以 通过观察开口(10)观察。
