Fakopp ArborSonic 3D Acoustic Tomograph
The ArborSonic 3D Acoustic Tomograph is able to detect the size and location of decayed or hollow regions in the trunk non-destructively. It works based on sound velocity measurements between several sensors around the trunk. The basic measurement principle is that sound velocity drops if there is a hole between two sensors.
Feature
- Drive the transducers through the bark using a rubber hammer with even spacing around the trunk.
- Measure the distances between the transducers with a caliper and enter the measured data to the computer.
- Tap each transducer with a steel hammer to generate sound waves. ArborSonic 3D measures the travel times with microsecond precision to each transducer and transmits the data to the computer.
- The software calculates and displays the internal sound-velocity distribution of the tree.
- Measurements taken at various heights can be assembled into a 3D model.
