ABSTRACT:
Method and apparatus is described for remote detection of location and intensity of clear air turbulence through the collection and analyses of back scattered laser light from a region where clear air turbulence may exist. The interference pattern of the collected light is determined through an ultra high resolution spectroscope and is analyzed with an image dissector. Information from the image dissector relating to the spectrum of back scattered light is correlated with the standard spectrum representing absence of clear air turbulence at the distance in question. By providing apparatus having high sensitivity and fast response, a device suitable for use in aircraft to detect clear air turbulence is provided.
