- LIDAR (LIght Detection And Ranging) is very similar to RADAR (RAdiowave Detection And Ranging) only instead of looking at "large" particles like rain droplets, airplaces or speeding motorists a LIDAR can see the "small" particles present in the atmosphere.
|
- The Development of LIDAR became possible with the invention of the laser (Light Amplification by Stimulated Emissions of Radiation)
|
 |
- monochromatic (one colour - one wavelength)
|
- collimated (very small divergence)
|
- very intense (lots of energy in a small area)
|
- polarized (energy is aligned in one direction)
