The optical and electro-optical requirements for on-line multi-component analysis of powder, granular and similar particulate solid materials are surveyed. The analysis is based on detecting small changes in weak nir absorption bands and the necessary photometric precision and spectral resolution are considered. Four alternative optical configurations are reviewed; filter wheel, tilting filters, spectral scanning and interferometer. Results obtained with the first of these are presented as a demonstration of the power of the technique and a number of possible applications presented.
