Applied optics·2012

Laser-induced breakdown spectroscopy (LIBS) effectively detects and discriminates landmines. This technology achieved over 90% accuracy in identifying landmines amidst soil and clutter, validating its field applicability.

Area of Science:

  • Analytical Chemistry
  • Spectroscopy
  • Remote Sensing

Background:

  • Landmine detection remains a critical global challenge.
  • Existing methods often struggle with accuracy and distinguishing mines from surrounding materials.
  • Laser-induced breakdown spectroscopy (LIBS) offers a potential non-contact elemental analysis solution.

Purpose of the Study:

  • To evaluate the efficacy of LIBS for detecting and discriminating landmines.
  • To assess LIBS performance using both laboratory and man-portable systems.
  • To analyze LIBS spectral data against various landmine types and common clutter objects.

Main Methods:

  • Collected LIBS spectra from diverse landmine casings, non-mine plastics, rocks, soil, and metal objects.
  • Conducted blind laboratory tests comparing spectral data to a reference library.

  • Utilized a linear correlation approach for mine/no mine classification.
  • Tested a prototype man-portable LIBS system under realistic conditions.

    • Main Results:

    • LIBS successfully discriminated between landmine casings and various clutter materials.
    • Over 90% accuracy was achieved in "mine/no mine" determinations during laboratory tests.
    • The man-portable LIBS system demonstrated comparable performance, validating field potential.

    Conclusions:

    • LIBS technology is a viable tool for landmine detection and discrimination.
    • The approach shows high accuracy and potential for field deployment.
    • Further development of man-portable LIBS systems can enhance demining operations.
