| Abstract: | A P.I.V. instrument using two synchronized CCD video cameras is described. The same field of view is imaged onto each CCD array with an image splitter and one imaging lens. The delay between two exposures can be adjusted from 0.5 to 20 ms depending on the flow velocity to be measured. Received: 12 February 1999/Accepted: 20 March 1999 |
