Abstract

The invention relates to an optical identifier (1) comprising an identification layer (3), in particular a physical unclonable function, and a sensor layer (4). Sensor areas (7) present in the sensor later (4) for detecting an identification signal (21) generated by said identification layer (3) in response to an irradiation beam (12), are relatively small in relation to the spatial frequency of the identification signal (21). In particular, since available sensors may not fulfill such requirements, it is proposed to provide a mask (5) is between said sensor layer (4) and said identification layer (3) comprising a plurality of holes (6) allowing the identification signal (21) to pass through the mask (5) and hit the sensor areas (7) is exhibited to said identification signal (21).
