Abstract
The influence of temperature fluctuations of the reference section of an optical fiber as part of the instrumental part on the absolute measurement error of a distributed fiber-optical temperature sensor was performed. The design of the reference section with active temperature control with high stability as part of the instrumental part of the sensor is proposed and experimentally investigated. The efficiency of using active temperature control to improve the repeatability of measurements and reduce the measurement error has been experimentally demonstrated.
