The sensor of microdisplacement based on change of faraday rotation angle of light in the optical light conductors
Influence of microbends of single-mode fiber light conductors on faraday rotation angle in light conductors has been studied. It is shown that leaving single-mode quartz and single-mode microstructural fiber light conductors elliptically polarized light is observed. Its ellipse of polarisation tests monotonous rotation at increase in size of microbends with sensitivity of 0,82 degrees per micrometer for quartz and 0,5 degrees per micrometer for microstructural optical light conductors.
