Landmines Detection Presentation Transcript:

1. 15,000-20,000 landmine victims per year By comparison, average of 700 annual deaths and 2,200 injuries due to terrorism over past decade 70% of victims are civilians One-third die Others lose limbs and/or vision

2. Solving the Problem:
Good News and Bad News Good news: 100,000 mines cleared each year Bad news: Clearing the 50 million existing mines will take 500 years and $14-50 billion Despite global ban, 1 million new mines are laid annually Thus, problem is getting worse: 10 times more mines are laid than cleared each year Potential good news: Innovative mine detection technologies could significantly accelerate demining and decrease costs

3. ANTI-PERSONNEL – DESIGNED TO KILL OR MAIM DISMOUNTED TROOPS ANTI-TANK - DESIGNED TO DESTROY OR DISABLE TRACK OR WHEELED VEHICLES CHEMICAL - DESIGNED TO DISPENSE SMOKE, CS OR MORE DANGEROUS BIOLOGICAL OR CHEMICAL AGENTS

4. Electromagnetic methods
Acoustic/seismic methods Chemical vapor detection methods Bulk explosives detection methods

 5. X-RAY BACKSCATTER
When X-rays pass through matter they will be attenuated, i.e. absorbed or scattered. The probability of scattering in the back direction. This probability depends inversely on the absorption power of the material to the incident and to the backscattered x rays. Organic materials typically absorb only a small fraction of the x rays, so that the scatter probability is high. Metals typically are strongly absorbing, and the scatter probability is low. Thus, organic materials are bright and metallic objects are dark in the image

6. capabilities and advantages :
1 . The information depth is sufficient to detect all regularly placed mines. 2. XBT is able to detect metal-free landmines. 3 . landmines buried in a variety of soil conditions including various types of vegetation will be detected with XBT.

7. Acoustic-to-seismic
wave-coupling approach to detect buried land mines. Acoustic sound waves penetrate the soil surface to generate seismic waves within the soil. These seismic waves cause the mine to vibrate and resonate, producing a displacement velocity field at the ground surface above the mine. This displacement can be measured by a laser vibrometer or UHF radar

8. Biological detector
If honeybees can be trained to seek the chemical components of explosives, the ability to track bees and analyze their hives could help pinpoint landmines or unexploded ammunition on firing ranges or old battlefields

9. Nuclear quadrupole resonance (NQR)
Nuclear Quadrupole Resonance (NQR), a derivative of NMR, is a bulk inspection technology which can be used to detect certain chemical elements which have a magnetic dipole moment. Amongst these is nitrogen-14 (14N) which is a major constituent of explosives used in landmines, such as RDX and TNT. NQR has been described as "an electromagnetic resonance screening technique with the specificity of chemical spectroscopy" as it not only detects but can be used to identify the exact chemical compound used.
