Velocity profile sensor using a frequency modulated laser diode and a molecular absorption cell

Not Accessible

Your library or personal account may give you access

Abstract

The Doppler frequency shift of scattered light is detected by using an absorption cell. Evaluation of the 1st and 2nd harmonics of amplitude modulated light yields the Doppler frequency without power influences.
