Abstract

The fiber optic vibration sensor consists of optic source, optical fiber, head and detection unit. The basic constructions of vibration sensors head consist of broadcasting and receiving optical fiber, plus modulator of transmitted radiation. Bar type configuration is mechanical modulator most often. This bar can be broadcasting optical fiber or make up of separate component. The vibratory component behavior can be described across reduction of mechanical arrangement to following parameters: supplementary mass plus elasticity and damping constants. In the paper the coherent method of modeling of converter propriety and experimental estimate of his parameter's value was showed. The proposed method to obtainment information about attenuation constant uses propriety of mechanical oscillation as well as registration and image processing in the intensity domain. In the face of that this method characterizes low costs of experiment.
