MICRORESONATOR FIBER-OPTICAL SENSOR OF MAGNETIC FIELD Russian patent published in 2000 - IPC

Abstract RU 2157512 C1

FIELD: fiber-optical converters of physical quantities with use of micromechanical resonators excited by light. SUBSTANCE: collimation of beam interacting with microresonator 5 in fiber-optical sensor of magnetic field is conducted by means of fiber autocollimator 3. Change of parameters of measured magnetic field is coupled with change of characteristics of microresonator 5 leading to change of resonance frequency in system fiber-optical laser - microresonator. Fiber autocollimator 3 comes in the form of section of single-mode quartz light-emitting diode with spherical microlens formed right on butt of this light-emitting diode. EFFECT: design of microresonator fiber-optical sensor of physical values for measurement of magnetic fields. 3 cl, 1 dwg
