A technique for measurement of gas flow velocity using photothermal deflection spectroscopy is described. This technique is especially suited for measurements of very low velocities. An extensive investigation of the technique has been carried out. This all-optical technique is nonintrusive and has high degrees of spatial and temporal resolution.
