The development of sensors for hybrid rocket motors has lead to the use of near-infrared diode lasers for characterizing hybrid rocket plumes. Emission Spectra obtained can be used to calculate species concentrations and temperatures, both spatially and temporally, in rocket exhaust plumes. In this paper we report our findings from a study of the emission spectra of hybrid rocket exhaust plumes in the ultraviolet, UV, visible, VIS, and near-infrared, NIR, regions of the electromagnetic spectrum.
