Paper Abstract

Recent advances in both imaging spectrometers and CCD based multichannel detection systems have made possible optical process monitoring and control of several sites simultaneously using a single system. Developments in optical monitoring leading to the present state of technology are reviewed. The benefits of these new multisite systems are discussed both in terms of advances in process control they make possible and the cost reduction they represent.
