Properties of sensors for domestic defense
applications

• Sensitivity ? existing passive remote sensors,
• Fast (0.1-1 sec),
• Multi-chemical (weapon agents simulants),
• Robust few (or no) moving parts, no fine
  alignment,
• Simple to operate,
• Output easy to interpret,
• Low cost (low level of approval),
• Low energy (commercially available battery),
• Imaging capabilities (desirable).
