Abstract

Light scattering techniques for velocity and particle size analysis are well established research and industrial tools. In general, light scattering instruments have been large and expensive, requiring skilled operation. The authors have constructed and tested a range of light scattering instruments in miniature form using semiconductor laser diodes, avalanche and PIN photodiodes and optical fibres. Thus it has been possible to demonstrate laser Doppler and transit anemometers for turbulent flow analysis and dynamic light scattering instruments for particle size analysis all of which are small and cheap enough to be of value in on-line process monitoring and control. The important features of the technologies used are described and industrial applications (biotechnology, pharmaceutical, automobile, aerospace, chemical), are discussed
