Abstract

A new technique which determines the location, behavior and velocity of particles with different shapes and sizes has been developed based on a Multiplexed Matched Spatial Filter (MMSF). The technique can be used in the manipulation or discrimination of the blood cells and the living cells in the liquid flow. The particles passing through on the frontal focal plane of the Fourier transform lens, the auto-correlation peaks can be observed skew-symmetri- cally for the input location at each observing field on the back focal plane of the imaging lens. The velocity of particles in each shape or size has been determined from the velocity of the displace- ment of auto-correlation peaks obtained by the MMSF method.
