1. A detector for object authentication, comprising:
a first illumination source being configured for projecting at least one illumination pattern comprising a plurality of illumination features onto a surface of an object;
a second illumination source being configured for projecting an illuminating light beam onto the object;
an image capture device comprising at least one optical sensor having at least one light-sensitive area, the optical sensor being configured for determining at least one first image comprising a plurality of reflection features generated by the surface of the object in response to the at least one illumination pattern projected by the first illumination source and configured for determining at least one second image comprising two dimensional information associated with the surface of the object generated by the surface of the object in response to the illuminating light beam projected by the second illumination source; and
an evaluation device in communication with the image capture device, the evaluation device being configured for evaluating the first image and the second image, identifying at least one geometrical feature of the object based on the reflection features in the first image, determining at least one material property of the object based on the reflection features, and comparing the two dimensional information of the second image to data stored in a database for authentication of the object.
