摘要 |
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 ).
