Modalmetric Fiber Optic Sensor for Security of Collections

The main aim of the work is the integration of modalmetric sensor in one arm. The proposed sensor is a classical fiber optic cable whose measuring arm is upgraded with multimode sensor. The aim of the research is to assess the impact of modal changes for detection of mechanical disturbances and comparative assessment of detection capabilities of interferometer sensor, modalmetric sensor, and hybrid sensor for different types of excitations. The measurements concerns the area of fundamental research. The results can be used in the construction of sensors with corresponding characteristics and properties, especially to protect museum collections.
