The present invention relates to a security element for detecting authenticity, in particular of security documents, bank notes, valuable documents, coins, chips, useful objects, design elements, data carriers, and similar objects. The security element according to the invention comprises a first layer (101) that is transparent to light and that has an index of refraction n1 and that has a surface (108) on a first side (108) of the first layer (101), said surface having a structure (105), a second layer (102) arranged on the first layer (101) directly on the structured surface (108), said second layer having an index of refraction n2, wherein n2 ? n1, in particular n2 >> n1 or n2 << n1, and the transmittance T of the light through the second layer (102) varies depending on location in the second layer (102) according to a specifiable continuous function T = T(x,y), and x and y are location coordinates in a layer plane of the second layer, and a third layer (103), which has a luminescent material and is transparent to the light and is arranged on the side of the second layer (102) opposite the first layer (101) and is connected to the second layer (102) in a light conducting manner, or is arranged on the second side (107) of the first layer (101) opposite the first side of the first layer (101) and is connected to the first layer (101) in a light conducting manner. |
