Abstract
A photoacoustic correlation technique, inspired by its optical counterpart—the fluorescence correlation spectroscopy (FCS)—was tested for the first time, to our knowledge, to demonstrate the feasibility of low-speed flow measurement based on photoacoustic signal detection. A pulsed laser was used to probe the flow of light-absorbing beads. A photoacoustic correlation system of 0.8 s temporal resolution was built and flow speeds ranging from 249 to
