High-Speed Measurement of Complex Shaped Parts by Laser Triangulation for In-Line Inspection,rallelizing this process by acquiring multiple points at the same time. A brief overview of methods with high measurement speed is given. The concept of optical triangulation is discussed in detail, and case study is presented to illustrate an implementation in industry of a dedicated measuring system for high-speed measurement of complex shapes.

X-Ray Computed Tomography for Dimensional Metrology,awbacks still limit a wider acceptance of CT in industrial metrology. One of the most critical aspects is the establishment of metrological traceability, which is often challenging due to many and complex error sources that affect CT measurements and complicate the evaluation of metrological performances and of task-specific uncertainties
