This book deals with the analysis and quantification of natural and manmade phenomena which are normally unseen to the eye. The two important tools of the trade are Visualization and Imaging.
Visualization is an old art of transforming normally invisible phenomena into visual events by utilizing, for example, fluid or solid tracers, or by changing wavelengths and refractory techniques. Reynold's original experiments in which colored tracer streaks allowed him to distinguish between laminar and turbulent flows is probably one of the first recorded quantitative visualization studies. Visualization techniques are usually applied to dynamic flow fields and are most powerful in the investigation of fluid mechanics and turbulent structures.
Imaging, similar to Visualization, converts unseen phenomena into visual entities. Generally, Visualization identifies and transforms physical entities into visual elements in the field under study, while Imaging involves recreation of the image of the physical entity from data-sets generated by the various imaging techniques. Obviously, the imaging process involves a visualization stage, which may explain the common interchange of the two terms. Thus, while computerized tomography (CT) is clearly an imaging procedure which utilizes x-rays, the standard x-ray which is a straight forward Visualization technique showing physical entities is commonly referred to as an imaging procedure.
