Stereo imaging

This approach is more close to X-ray stereo imaging and caimot reach enough depth resolution. There are also several systems with linear movement (1-dimensional) through the conical beam [5] as shown in Fig.4. In this case usable depth and spatial resolution can be achieved for specifically oriented parts of the object only. 

A film image is of course 2-dimensional and the bars are thus projected onto the film without knowledge of their depth from the surface. If the angle of projection is not perpendicular to the film then there may be considerable distortion of the projected images, as is often the case with concrete - typical object (reinforcing) film distances may be 150 mm. The problem can be solved by stereo-imaging but this is ineffective and expensive.

Stereo image of a ball-and-stick model of sialic acid bound to the active site of Tern/N9 neuraminidase. The hydrogen-bond interactions with conserved residues are shown as dotted lines. Nitrogen atoms are shaded black, oxygen atoms are shaded dark gray, and carbon atom are shaded light gray. 

Stereo image of the active site of Tem/N9 showing the active-site residues surrounding 4-guanidino-Neu5Ac2en (black). Those residues that are conserved in both influenza and bacterial neuraminidase are shaded gray, and those that are conserved only in influenza virus neuraminidase are not shaded. 

These two renderings of methane are stereo images—you can see them in three dimensions by looking at them cross-eyed so that they appear to overlap. You can think of this three-dimensional structure as follows the central carbon atom has one hydrogen atom sticking out of its top and is supported on a tripod whose legs are formed by the three lower C—H bonds. 

The precedence effect describes the effect that sound sources are sometimes localized not according to the loudness of left versus right channel but on the origin of the first (not the loudest) wavefront. This time relationship between signals can be distorted by certain joint stereo coding techniques resulting in an altered stereo image.
