抄録

A new technique which can measure the spatial distributions of spherical particles in each size range has been developed using reflective type Multiplexed Matched Spatial Filtering method. In experiments, the two dimensional spatial distributions of size of spherical particles were measured by a Multiplexed Matched Spatial Filter (MMSF) made from the arrangement of several numbers of reference patterns having about ten times difference in those diameters of particles. It was clarified in the experimental results that the sizes of particles being able to be discriminated by each reference size of particles were within the limit of about ±15 % of each reference size of particles in a MMSF. The auto-correlation peaks were located skew-symmetrically for their input positions in each size recognition field of reference particles. The discriminable size range by one MMSF was over ten times difference between the minimum and maximum size of particles.
