FIELD: measurement equipment.
SUBSTANCE: invention relates to facilities of automatic identification of objects. The automatic identifier of objects comprises a body with an outlet window made in it. In the body there is a photodetector, an electric unit of processing, saving and comparing of outlet signals of the photodetector, an optical tract, formed by an outlet window, a collecting lens and a source of light from several light-emitting elements that operate at frequencies of optical range. The identifier comprises a unit of control of modes for connection of light-emitting elements depending on the material of the surface of the controlled section and/or logic of optical image reading. Light-emitting elements are installed along the perimeter of the inner surface of the body in close proximity to the bottom of the body, in which there is an outlet window, and are placed so that the longitudinal axis of symmetry of the light beam created by each element passes along the normal line or in a direction close to it in respect to the axis of symmetry of the optical tract.
EFFECT: increased quality of an image of a controlled section and energy saving.
