This chapter will cover four of the commonly used methodologies for particle measurement, that is static light scattering, dynamic light scattering, RGB multi-wavelength light extinction and ultrasonic scattering. For each of these methodologies, the measurement principle, data processing or inversion algorithm, experimental system and some measurement results are included.
