Fiber Optic Sensory System for Area Perimeter Guarding with Speckle Detection
Original language description
Vibration detection is widely used in many areas in our everyday life. Several methods exist to measure vibration. Particularly interesting is to use light propagating in optical fiber for spatially distributed or locally induced vibration measurement. This paper deals with the results achieved in currently running project that aims to test and practically implement vibration sensors using optical fibers with detection of spatially filtered speckle light patterns of multimode fiber driven by a coherentlaser source light. Primary anticipated area of practical implementation is continuous guarding of critical infrastructures. In aforementioned project we are using the multi zoned speckle detection so that an intrusion event can be identified only per zone as whole and not yet at specific position in the zone itself. The results show that a speckle analysis is potentially applicable as an inexpensive method for sensing vibrations with optical fibers if suitable spatial light filtering at
