Paper Abstract

An understanding of the phenomenon of light scattering by small particles has existed for more than one hundred years. The application of that knowledge to particle size measuring instruments has been common for more than fifty years. Many of those early instruments were based on the scattering of white light, often simple extinction measurements. The situation today is one of widespread use of laser measuring techniques in a wide variety of industries. Currently the preponderant use is laboratory based but now is the time that an extension to on-line monitoring and control is possible and will certainly occur. Three technologies which have developed enormously in the past twenty five years have made this possible. Those three developments are the laser, the optic fibre and the computer which have combined to completely revolutionise both the capabilities and the importance of light scattering instruments in industrial applications.
