Abstract
Coherent laser radar (CLR) systems have been investigated over several decades primarily for military applications. Depending on the application, several design parameters, e.g. the choice of system technology and wavelength, have to be considered. A short wavelength system can give advantages in robustness and size whereas a long wavelength system can give advantages in a lower attenuation by aerosols, which results in a longer range. Applications for a multi-purpose system a CO2-ladar include, e.g., range finding, vibrometry, and 3-D imaging. A CLR system is very useful for remote sensing of vibrational and rotational characteristics of surfaces and objects. Such information can be used in e.g. inspection and maintenance of helicopters and aircraft, and also for platform identification.
