Abstract

The design and performance of a photon counting, two channel spectroscopic system using a CW argon ion laser is described. The system measures either the concentration of two gas species in a cold flow or the temperature and concentration of a single gas species, such as nitrogen, in a flame. The intensities of two Raman lines with spectral bandwidth between 0.04-0.08 mm are recorded. A mini computer can record at a sampling rate of up to 10 kHz. Studies of a methane diffusion flame at sampling rates of 20-100 Hz at room temperature, axisymmetric carbon dioxide jet at rates up to 2.0 kHz were carried out. Analysis of the data is discussed.
