1. LADAR Image Visualization Tool By: Robin R. Burton

3. 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

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

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

6. Function of Wavelength

7. Data Structure R1R1 R2R2 R3R3 R4R4 R5R5 R6R6 y1y1 x1x1 1 R1R1 R2R2 R3R3 R4R4 R5R5 R6R6 y1y1 x1x1 2 Down a pixel (Range) Peak of Absorption Feature Wing of Absorption Feature 1 2 Across cubes (Spectra)

8. 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

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