Real time Doppler imaging system using forced vibration of the object
Abstract
Doppler imaging systems are improved by introducing forced vibration of objects, by pulsed laser illumination in synchronism with it, and by suitable signal processing and color display of the final image on a TV monitor. In this way physical quantities, such as diameter or relative density of particles, can be transformed into the amount of the Doppler shift. This idea is used to construct a real time Doppler imaging system which displays the particles classified according to their physical properties and distinguishes them by different colors.
