Abstract

This article relates generally to computer graphics and, more particularly, to enhancement of surface features displayed by scanning devices. Data generated and displayed by two dimensional scanning devices can be enhanced with real time, computer-generated fictitious light sources and light-scattering models to produce photographic quality images. The output signal level of conventional scanning devices, such as the scanning electron microscope, scanning transmission electron microscope, scanning tunneling microscope and other medical imaging systems, when combined with a false surface representation, adds clarity and prominence to obscure surface features. An example is illustrated in Figs. 1 and 2 which illustrate the (Image Omitted) character of a thin gold film on an amorphous substrate. Fig.

Enhanced Surface Displays

This article relates generally to computer graphics and, more particularly, to enhancement of surface features displayed by scanning devices. Data generated and displayed by two dimensional scanning devices can be enhanced with real time, computer-generated fictitious light sources and light-scattering models to produce photographic quality images. The output signal level of conventional scanning devices, such as the scanning electron microscope, scanning transmission electron microscope, scanning tunneling microscope and other medical imaging systems, when combined with a false surface representation, adds clarity and prominence to obscure surface features. An example is illustrated in Figs. 1 and 2 which illustrate the

(Image Omitted)

character of a thin gold film on an amorphous substrate. Fig. 1 shows a standard scanning transmission electron micrograph, and Fig. 2 shows the same view with a false surface representation using fictitious shadowing and light scattering where the intensity in Fig. 1 was used to determine surface height. A surface display can likewise be tilted. The quantity Q (x,y) being measured can either enhance, reduce or invert height variations. Likewise, the viewing and illumination angles can be adjusted or the color of regions can be varied to illustrate selected features.
