Abstract
A compact and transportable infrared multicomponent acquisition (IRMA) syst em based on infrared absorption spectroscopy has been developed for plasma diagnostics and control. The IRMA system contains four independent tunable diode lasers which can be temporally multiplexed and directed into plasma r eactors or into a multipass cell for exhaust gas detection. Rapid scan soft ware with real-time line shape analysis provides simultaneous measurements of the absolute concentrations of several molecular species. (C) 2000 Ameri can Institute of Physics.
