<title>Composite sensor based on sapphire-quartz fiber optic cantilever micromechanical vibration</title>

Abstract

Composite optical fiber cantilever micromechanical vibrated sensor is considered. Usual quartz fiber is supplemented by crystal sapphire fiber part which have high Q-factor of mechanical oscillations. Sensitivity of the Bragg-gratings with yr-phase shift at the end of the fiber cantilever are discussed. Keywords: fiber, cantilever, mechanical vibrations, fiber grating.
