Abstract

We have developed a technique well suited for gaseous flow field visualization using laser induced fluorescence (LIF) coupled with an array detector which allows us to obtain real-time spatial profiles of fluorescence from iodine seeded gas jets. Furthermore, array detection provides signals that are linear in fluorescence intensity as well as producing data ammenable to digital signal processing.
