Abstract

The paper deals with the influence of birefringence on the change of polarization and the change of frequency in sensory optical fibers. The aim of the described research was to design and implement a set of measurements that analyze these influences. The article builds on research that has dealt with this issue in the past and offers some simplifications in the design of the measuring station, describes control measurements and analyzes in detail the response of light parameters at the sensor output to changes in temperature. The article presents, compares and discusses the results of intensity changes at individual wavelengths, which demonstrate changes not only in the instantaneous polarization state of light but also changes in wavelengths with maximum light intensity depending on temperature changes. These principles can then be used to advantage with Military, Biomedical and Physiological Sensors Systems.
