FIBER OPTIC INTERFEROMETER AND METHOD FOR DETERMINING PHYSICAL STATE PARAMETERS IN THE INTERIOR OF A FIBER COIL OF A FIBER OPTIC INTERFEROMETER |
摘要 |
<p>A fiber-optic interferometer comprising an optical fiber wound to form a fiber coil into which two partial light beams of a first light source can be coupled. The Bragg structure is integrated into the fiber coil. Said Bragg structure comprises an optical fiber having a periodically varying refractive index. In a method for determining physical state parameters in the interior of a fiber coil of a fiber optic interferometer information about physical state parameters in the interior of the fiber coil is obtained on the basis of the reflection wavelength of a Bragg structure comprising an optical fiber having a periodically varying refractive index is integrated into the fiber coil.</p> |
