DAS / Differential Absorption LADAR (DIAL)

• Technique
• Ratio of the peak of an absorption feature to the
  wing of the same feature
• Many molecules have narrow features in the 5-12
  ?m region
• Used to uniquely identify specific molecules
• 3D concentration maps
• Using assumptions
• Density
• Pressure
• temperature
• Uses tunable lasers

9
Topographic

• Scatter off a solid target
• Laser rangefinder
• Can create digital terrain elevation maps
