Some recently developed optical methods for the measurement, control and shape recognition of particle flow are presented including motion control of micro‐particles by optical pressure, identification of particle groups by matched spatial filters, bidirectional light scattering/image processing, bidirectional light scattering/real time measurement, dual beam type particle counter, and speckle photography.
