Abstract

Two-dimensional light slicing is obtained by passing a filament of light through a segment of a cylindrical lens. This produces a lamina of light that can be used for 2-D imaging of fluid flows. The method has advantages over shadowgraph, schlieren, and interferometry techniques, since line integration of optical properties along light rays is evaluated only through the section of a thin illuminated lamina. Computer-aided design of the system and a laboratory arrangement are presented. Applications for the examination of transient gas jets are shown.
