Abstract

Bevegelsen av partikler som bæres med i et fluid, påvises ved at et område av fluidet isonifiseres med pulser av ultralyd. Pulser av ultralyd spredt av en enkelt partikkel påvises fra påfølgende utsendte pulser og forkjellen i ankomsttidene for påfølgende påviste pulser henføres ganske enkelt partikkelens hastighet. Utnyttelse av egnede porter (A, B) gjør det mulig å etterspore påfølgende refleksjoner fra en partikkel mens refleksjoner fra andre partikler forkastes.
