FIELD: physics.
SUBSTANCE: device comprises a reading head equipped with a system for focusing laser radiation for exciting NV centres in a label, configured to create on the surface of the label a focal spot which is strongly stretched in the direction of movement and has a smooth intensity distribution profile along said direction. Furthermore, for microwave excitation of the label, the reading head is equipped with a short-circuited section of a double-wire line, and for collection of fluorescence radiation with a linear array of optical fibres, lined up along said focal spot.
EFFECT: reduced false triggering of the device with simultaneous expansion of the field of use thereof on the label.
