METHOD OF MARKING AND IDENTIFICATION OF OBJECTS Russian patent published in 2002 - IPC

FIELD: methods of recording radiations. SUBSTANCE: identification sign is applied on abject for individual identification which is illuminated by two emission impulses: first impulse for recording luminescence radiation (duration of radiation, optical spectrum of luminescence and dependence of intensity of luminescence on time) and second impulse for recording said parameter in monitoring. Then, parameters after first radiation and after radiation during monitoring are compared. Illumination of identification sign is effected by emission impulse of large duration of lighting-up of any luminescing ingredient. EFFECT: increased intensity of luminescence light at excitation of luminescence of identification sign and reduced intensity of reflected light getting into photodetector. 10 cl
