This chapter describes the radiation phenomena that occur during fuel/oxidizer reactions; specifically the ultraviolet (UV), visible, and infrared (IR) light that is emitted via a variety of mechanisms during combustion events. Significant information about combustion can be acquired by analyzing the light-emission profile of combustion events. Techniques such as emission spectroscopy, two-color optical pyrometry, radiation thermometry, and combustion visualization are all utilized to study combustion. Both, sooting and nonsooting flames can be studied effectively with light-emission techniques. The inherent advantage to utilizing emission-based techniques to study combustion is that they require only minimal access to the combustion event; only a method is needed for light to leave the measurement area, such as fiber optics, endoscopes and borescopes, and small windows. Explanations of each of these techniques and their advantages/disadvantages in different applications will be discussed.
