Impact of fixing materials on the frequency range and sensitivity of the fiber-optic interferometer

Popis výsledku v původním jazyce

Fiber-optic sensors are one of the dynamically developing areas of photonics, which is today one of the key technologies. Here include even fiber optic interferometers, allowing very sensitive sensing, they are immune to electromagnetic interference and are entirely passive regarding electric power supply. This type of sensor is dependent on the phase shift, the principle of the function based on interference of light. Fiber optic interferometers are used especially in areas that require high sensitivity and measurement accuracy. The fundamental problem of fiber optic interferometry is a proposal storing and fixing the measuring arm of the interferometer and its influence on the frequency range and sensitivity of the interferometer. The authors focused on this issue and analyzed different types of fixing materials. We used a total of 8 different fixation elements with the different composition. We defined the standardized method of fixation and compared it with a reference measurement without fixation. For the analysis of the frequency characteristic of the prototype was used generator harmonic signal with fixed amplitude signal. Sensitivity verified using the size of the amplitude response. The signal processed by the application written in LabView development environment. The results clearly showed that it is necessary to pay attention to fixation materials in the design of the measuring arm of the interferometer for use in practical applications. In the frequency range, thanks to the fixing material increased the value of bandwidth about value 2430Hz against the reference measurements. The sensitivity of the interferometer has increased threefold. The results verified by retesting assembled prototype.
