FS-Reflexion

FS-Reflexion is a geophysical measuring instrument to locate subterranean voids like caves, bunkers, tunnels or basement vaults. FS-Reflexion works with a seismic vibration system. A transmitter generates vibrations going into the ground. Depending on the type of soil they will be transmitted or damped. If a void exists it will start to resonate in its own frequency and can be detected by a seismic vibration transducer. FS-Reflexion can be used all around the world, no matter if there is stony ground, loam or clay soil, in the mountains or in flat country.

• Check Mode to recognize seismic disturbances
• Scan Mode to record measurement values for a graphical representation
• Frequency-energy-graph to analyse seismic activities
• Data transfer to computer for graphical representation in 3D

The recorded measurement values can be analysed via the frequency-energy-graph. In this diagram a high amplitude at specific frequencies indicates existing subterranean voids. Additionally it is possible to summarize all measurement values to a 3D representation, so that they can be analysed in the professional Visualizer 3D software. In that way voids cannot only be represented visually, but also their size can be determined.
