KEYENCE LK-G Series CCD Laser Displacement Sensors measure height, position, thickness, warpage, profile, runout, and vibration on any material/surface. They also measure fast moving, vibrating or rotating objects.

How do they work? What are the technical factors that contribute to their accuracy, linearity and repeatability? How can you use them?

A 14 page illustrated book describes the principles of laser triangulation, measuring distance, accuracy, stability, optical design, measurement of different surfaces and lots more. More info
