Abstract
Perspective view of vortex structure in a fully developed region of a circular jet is reconstructed by applying a digital image processing to cross sectional pictures visualized using laser-induced fluorescence. The time of motion pictures is converted to longitudinal position by Galilean transformation of which constant is a convective velocity of the structure. A fast image stacking system using a personal compuer and a video image memory board is developed, and the resultant three-dimensional pictures are examined by stereoscopic display using liquid crystal shutter glasses.
