Abstract
A clear air turbulence detector includes an ultraviolet laser for generating a coherent beam which scans an area on an aircraft's flight path. A photodetector monitors optical radiation backscattered from the area, providing an intensity-controlling electrical signal for a CRT display. Updrafts contain greater-than-normal amounts of ultraviolet-absorbing water vapor and result in a blank spot on the display while downdrafts contain less-than-normal amounts of water vapor and result in a bright spot on the display.
