title: Real time Doppler imaging system using forced vibration of the object.
abstract: Forced vibration of objects is used to transform physical quantities into the amount of the Doppler shift. By combining this with a real time Doppler imaging system, a method of real time imaging of classified objects is proposed. As an example, particles are vibrated through the vibration of a water cell, which includes the particles in it. The possibility of real time display of these particles classified according to size or weight is discussed. The display of particles of different size or weight by distinct color on a TV monitor in real time seems most interesting.
