Abstract
This presentation will focus on the design and functional aspects of three-dimensional (3-D) imaging systems. AS a starting point performance characteristics will be discussed. These include: depth resolution and accuracy; lateral resolution, repeatability and accuracy; reflectance, sensitivity; working range; standoff; occlusion angle; and measurement rate. The performance of a given three-dimensional imaging systems will depend on the trade-offs made during the designing. process. Of course, some techniques are intrinsically better than others in certain performance areas. When classifying the various techniques for three-dimensional imaging they can be broken down into scanning and non-scanning approaches to producing full-field three-dimensional imagery. Systems that employ scanning include point triangulation and laser radar.. lion-scanning techniques include stereo imaging and moire, interferometry. The discussion of these techniques will focus on the strengths and weaknesses of each and the design considerations when building or using the technology.
