About This Webinar
Recent years have seen a growth of 3D optical metrology tools able to map objects, some big like buildings and others small like microbes. Making sense of what tool can do what task can be daunting to anyone not very familiar with the technology used and the limitations of each 3D method.

This presentation reviews the basic technical mechanisms of the many 3D optical metrology systems available and looks at both the strengths and limitations of each tool on a technical basis for applications ranging from meter sizes to microns.

Issues considered will include practical considerations of part access, surface quality, and geometry limitations with tradeoffs of these issues against practical measurement ranges and resolutions. The results provide a valuable starting point for picking the right 3D optical metrology tool for whatever task is required.
