The measurement of the strength and velocity of atmospheric optical turbulence using a generalised SCIDAR technique is outlined and demonstrated. This method allows the full turbulent profile to be characterised from the telescope pupil up to any desired altitude. A number of example profiles from various astronomical observing sites are presented.

Key words: atmospheric effects -- site testing -- telescopes
