A reacting system can be fully specified with high spatial and temporal resolution measurements of species number density, temperature, density and velocity. Various instruments exist that satisfy the limited volume and power environment and rigors of the experimental migrogravity research environment; collectively these instruments provide many of the measurements needed to fully specify combustion systems. Of those instruments, those for major combustion species currently include probe sampling techniques and absorption and emission spectroscopy. Probe techniques cause flow perturbations and have slow time response, while, absorption and emission spectroscopy require constant species densities along the line of sight, or inversion techniques to extract quantitative data with spatial resolution. A Vibrational Raman Spectroscopy instrument is described that would enable spatially resolved measurements of major species number density for use in microgravity combustion. The instrument utilizes an intracavity tripled diode pumped Nd:YVO4 laser and detection via acousto-optical tunable filtering with a PMT operating in photon counting mode. The instrument is capable of single point sub-100 ms temporal resolution and sub-mm spatial resolution.
