In recent years, the need for nonintrusive diagnostics of gaseous flows has motivated the development of optical techniques such as LIF, which is the most attractive method for an analysis of the flow field structures. IfO 2-LIPF is feasible to visualize air flows, no seeding of the flows and no consideration of toxicity and corrosiveness may be required. However, since the fluorescence of oxygen molecules is very weak and in the ultraviolet region, there may be some difficulties in detecting the fluorescence signal. In this study, a system is developed to visualize supersonic oxygen flows using O 2-LIPF, which consists of an ArF excimer laser, a high-sensitivity CCD camera and an image intensifier. Three spectral filters are selected to eliminate the scattered laser beam, and three images visualized through them are compared.
