HARVARD , USA – Red Lotus Technologies have come forth with an innovative and efficient technique for detecting landmines. Called PETALS, which stands for Pattern Enhancement Tool for Assisting Landmine Sensing, it makes use of acoustic sensors to differentiate between junk metal like buried tin cans from actual landmines.
This is accomplished by mapping the beeps given out from a metal detector on a smartphone’s screen to create a silhouette of the buried object, as the metallic field of a buried object is roughly equal to its size and shape. This eliminates much of the guesswork and the need of extensive training, as earlier de-miners had to rely entirely on the intensity of beeps.
Although such technologies have been tested in the past, PETALS is significant because it can harness the power of regular smartphones instead of dedicated devices. Affordability, lightweight design, weather resistance, 3-hour uninterrupted operation and compatibility over a variety of sensor models are among the major advantages of PETALS.
Red Lotus Technologies has already conducted an initial research project on PETALS, and is now moving on to tablet-based training equipment. Novice de-miners have exhibited an 80% performance improvement in using PETALS, and the company hopes to field-test such devices in Cambodia before their official launch.
