dc.description.abstractThe development of centimeter to millimeter scale engines and power supplies have created a need for micro-scale combustion diagnostics. Fuel concentrations, product concentrations, and temperature are useful measurements in determining combustion behavior, chemical efficiency, and flame structures. However, to the present there have been few efforts to develop non-intrusive diagnostic techniques appropriate for application in such small engines. Non-intrusive measurements in these engines are complicated by short path length and lack of optical access. In this thesis in situ FTIR spectroscopy is used to measure temperature and concentrations of fuel, and carbon dioxide in a micro-combustor. The measurements are made through silicon walls spaced a few millimeters apart. This is possible because silicon is transmissive in the infrared. Experimental issues, including the optical setup, limitations associated with etaloning, calibration, and interpretation of the resulting spectra using wide-band models are discussed in detail.en_US
