摘要：A device for examining an object, preferably a document of value, by usingoptical radiation, having an optical waveguide which has an anisotropic retro-reflectorsection, which is formed along a surface curved in a plane of curvature and which reflectsradiation components specularly in a first plane of incidence parallel to the plane ofcurvature but retro-reflects radiation components orthogonally with respect to the firstplane of incidence, so that at least a proportion of the optical radiation falling in aglancing manner on the retro-reflector section is at least partly guided on the convexside of the surface by reflection on the retro-reflector section.
