- DPI designs and produces 3D shape scanners and software.
- Shape scanners snap 3D photos of objects almost as simply as a digital camera snaps (2D) photos.
- 3D photos are essentially CAD (computer aided design) models of actual objects or a 3D "topographical map" of the surface of the object.

- Our "3D photos" are accurate to microns and can be generated in real time. (A human hair is about 20 microns thick.)
- Our shape scanners can be used in a variety of applications. For example, we can directly create a CAD model of an object (reverse engineering), we can compare a scanned object to its associated CAD model (inspection), we can monitor changes in objects that are manufactured on assembly lines (process control), and finally, we can scan objects for the simple purpose of communication (visualization).
- Our shape scanners are based on technology originally developed at Massachusetts Institute of Technology (MIT) Lincoln Laboratory, and on many technological breaktroughts made by DPI.
- The fundamental technology is called Accordion Fringe Interferometry (AFI). AFI has distinctive characteristics likely to establish it as the dominant technology for many area scanning applications around the world.
