FS-Reflexion

on April 29, 2020

FS-Reflexion is a geophysical measuring instrument using the methods of seismics to locate subterranean voids and cavities like caves, bunkers, tunnels or basement vaults. During the active measurement procedure, vibrations will be generated and transmitted into the ground. As a result, reflexions, travel time and vibrations can be recorded. According to the soil conditions the measured data give clues to hidden objects.

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 these 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 on all kinds of underground, e.g. stones, loam or clay soil, in the mountains or in flat country.


FS-Reflexion operating modes

  • 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

FS-Reflexion data analysis

The recorded measurement values can be analyzed 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 software Visualizer 3D. In that way, voids cannot only be represented visually, but also their size can be determined.
