The Fiber-Optic Sensor for the Museum Collections Protection

The article describes the operation's rule of the fiber optic sensor in the modalmetric configuration. This type of sensor is described by comparatively simple construction, while retaining other features of fiber-optic sensors such as high sensitivity. This gives a very high potential application. In the paper possible application of the modalmetric sensor to protection of works of art and museum collections is presented. The advantage of its use is the ability to tie the fiber in structure of material. Moreover, the advantage of such type a sensor compared to existing solutions of security sensors is the reaction for vibration and touch. The paper presents the concept and results of the system optimization.
