Optical instrument for thickness measurement

In modern metrology it is increasingly common to find the importance of thickness measurements in the production processes of compact materials (metals, plastics, paper, rubber, etc.). A quick and timely measurement is indispensable in those automated industrial processes capable of modifying the production parameters in real time in order to have the characteristics exactly suitable for the needs. The idea of the development of this kind of instrumentation it is starting from this. The requirements that the system will have to respect, including the importance of having a meter that must not be in contact with the plastic film and that can only be positioned on one side of it. These restrictions require the choice of a measurement methodology to be sought mainly in the optical field.
