Price: 50 руб.
 The article discusses the temperature compensation method of the fi ber optic electric fi eld sensor working on the Pockels effect in the lithium niobate crystal, wherein an optical waveguide was created. The experimental model was made to research the sensor with a sensitive element included in the scheme of the polarization interferometer. Modular instruments of the National Instruments Corporation and the NI LabVIEW programming environment were used for the generation and signal processing. The dependences of the sensor accuracy from sensitive element temperature were registered. It was able to identify two factors that cause essential errors in the measurements of the electric fi eld sensor. The fi rst factor is the polarization mismatch in elements of the optical sensor’s scheme. The second factor is a temperature change of the electro-optic coeffi cient of the material of the sensing element. The ability to reduce the infl uence of the fi rst factor and to compensate errors caused by the second factor has been demonstrated.
Keywords: fi ber-optic sensor, fi ber Bragg grating, electric fi eld measuring, temperature compensation.
