FIELD: measurement.
SUBSTANCE: invention relates to measuring equipment, namely to the creation of sensitive elements of spectral sensors and converters of physical quantities. Two additional structural elements are attached to the resilient element - heat-sensitive elements made of material, the value of the thermal expansion coefficient of which is greater than the value of the elastic coefficient of expansion of material of the elastic element. Fibre Bragg grating is fixed on said structural elements. Thermal elongation of additional structural elements - heat-sensitive elements compensates for temperature elongation of the fibre Bragg grating and, accordingly, temperature deformation of the Bragg transducer.
EFFECT: technical result is expansion of arsenal of methods for compensation of temperature deformations in Bragg converters of beam type.
