ABSTRACT:
A method for measuring a fluid flow includes employing small light-absorbing particles as tracers that flow at the same speed as the fluid, measuring the photoacoustic Doppler shifts of the photoacoustic signals produced by these tracer particles, and determining, from the measurements, information about the flow including one or more of the flow speed, flow profile, and flow direction.
