Standoff Detection of Explosives: IR Spectroscopy Chemical Sensing
R3-C

Use IR spectroscopy (IRS) to develop confirming (orthogonal chemical) sensors for detecting explosives residues on clothing, travel bags, personal bags, laptop bags/cases, skin and other substrates. Use after millimeter wave sensing of anomalies/devices under clothing and within human bodies. Based on:

  • MIR-QCL arrays for standoff reflectance; coupled to IR telescopes
  • Laser induced thermal emission spectroscopy (LITE; eye safe>1 m; test: 60m)

Relevance to the Homeland Security Enterprise

  • Detect/identify explosives: bulk (1 g) & near trace (sub-gram/cm²) @ 1-50 m
  • Technique should provide positive/negative or a confidence level indication to the operator for presence of explosives within 1 min
  • Operate effectively in a field environment from multiple distances with varying humidity, air particulates, temperature, light and wind
