ABSTRACT:
A micro-doppler ladar comprising a tunable laser to identify an unknown constituent of a gaseous cloud or region at a safe distance from the cloud or region. The tunable laser produces a laser beam tunable over a range of different frequencies. Each frequency produces a different vibrational response in the constituent in the gaseous cloud when the cloud or region is illuminated by the laser beam. A micro-doppler ladar system then interprets a back scattered beam to determine the induced vibrations. The determined induced vibrations can then be compared to known vibrations stored in a look-up table to identify the specific constituent(s) in the cloud or region.
