Abstract
A time of flight velocimeter wherein a radiation source projects two parallel beams into an air mass. Each of the parallel beams converges into a waist portion. As an aerosol particle moves through the waist portion, part of the radiation of each of the beams is backscattered. This backscattered radiation is focused onto two detectors, one for each beam. Signals from the detectors, generated in response to the backscattered radiation, are processed to determine the velocity of the particle which has passed through the waist portion of the two beams.
