Irradiance in the focal plane of a coaxial ladar system with central obstruction; obstruction radius 50mm, distance 100m Return as a function of position in the FP

Simulated return for a single pixel as a function of range (hard target return)

Simulated return for a single pixel as a function of range (aerosol return)

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 Peak of Absorption Feature Wing of Absorption Feature 1 2

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