FIELD: measurement equipment.
SUBSTANCE: this invention relates to the field of Brillouin optoelectronic measurement to use control of physical characteristics, such as deformation and temperature. The method and device for realisation of the specified method, includes a stage of signal provision in an optic fibre, besides, the specified signal is a signal with frequency-time coding. The signal with frequency-time coding may be an optical pump signal comprising a sequence of code words, each code word comprising at least two light pulses, each pulse of the code word is characterised by differing frequency.
EFFECT: improved efficiency of optoelectronic measurements with increased distance of action with available spatial resolution, ie minimisation of possible drifts during measurement of temperature and/or defromation.
