Paper Abstract

Recently interest has grown to the physical quantities fibre-optic sensors in which a micromachined resonator acts as a sensitive element. This resonator can change the resonant frequency when acted upon by an outside force. Energy supply necessary for the resonator excitation and transfer of information about the outer action are accomplished by optical fibres, that can be present in the zone of a higher aggressiveness, strong electromagnetic interferences atc. The frequency output of such sensors is easily processed by digital systems and is insensitive to signal level.
