Electro-optic holography (EOH) generates a large array of three-dimensional values (displacement at each x, y location) as its final output. In the past, a number of techniques have been employed to display the displacement data ranging from topographic maps and enhanced versions of the holograms themselves, through fringe skeletonizing, to wire frame surface plots. This paper discusses the application of 3-D shaded rendering techniques to holographic displacement data. Both modeling the object and rendering the model are covered. The resultant shaded images show the displacements of the surface clearly and the software allows the user complete control over the orientation of the view and the characteristics of the light sources. Results are shown for a number of modes of vibrating rectangular plates.
