Flow motion detection and analysis of 2-D and 3-D velocity fields in a fluid is a very important task in many applications, for example the study of fluidodynamics phenomena in microgravity conditions, i.e. in space environment. An extremely interesting technique useful to analyse fluids flow without introducing significative disturbances employs the change in optical density of some specific dyes when lighted with ultraviolet light. In this paper a complete processing system is described that uses the dye method to analyze fluid flow by means of digital image processing techniques.
