Abstract

We present a flexible architecture for particle sizing based on the VanderLugt correlator with a multiplexed matched spatial filter. Theoretical and experimenal data obtained using opaque spherical particle projections demonstrate the potential uses and simplicity of the architecture. The system is capable of handling spherical and nonspherical particles and shows potential for handling high particle concentrations.
