Principles of measurement

Thickness: comprised of two correlative laser displacement sensors. Those two sensors will make use of triangulation method, emit a beam of laser to the surface of measured object, measure the upper & lower surface position of the measured object by detecting the reflective position, and calculate the thickness of the measured object.

As shown in the figure below:electrode thickness C=L-A-B

Dimension: drive the synchronized CCD camera/ laser sensor through motion module + grating ruler to run from electrode head to tail, calculate the longitudinal length of electrode coating area, gap length, and length of displacement between head and tail of side A/B etc.
