Holographic interferometry as a diagnostic tool for reactive flows
The combination of the techniques of holography with those of interferometry has greatly extended the usefulness of interferometry and has resulted in one of the most widespread uses of holography. The purpose of this paper is to summarize the methods and state of the art of holographic interferometry as applicable to combustion and reactive flow diagnostics. Holographic interferometry, like conventional interferometry, provides a measurement of optical path length between points in space. This can be applied to determine gas density or to observe density gradients and their movement throughout a volume. Moreover, a holographic image of a space is not just limited to interferometric analysis. Such images are amenable to a broad class of optical analysis, not the least of which is the study of the distribution of material, such as fuel droplets, dispersed in three dimensions through the volume.
