Advantages of Optical Metrology For a variety of materials, especially those that are hot, elastic, highly sensitive, or ”dough-like”, it is impossible to use tactile sensors such as odome- ters or tacho rolls. The accuracy of a mechanical sensor system is also reduced by slippage, which in practice, can lead to measuring errors of 10% or more. In both cases, non-contact optical metrology provides significant benefits. The two complemen- tary type series COVIDIS and OPTIPACTproduced by INTACTON represent two different technology platforms, which can be used for a wide range of applications.

MEASUREMENTOF LENGTH AND VELOCITY

Field of Application In highly automated production processes, length and velocity data are required for manifold purpo- ses. For instance, measurement of operational throughput delivers essential data to control pro- cess parameters. In packaging applications using strip material, length measurement controls the cut- ting process. In the manufacturing of piece-goods an automatic start- and end-recognition mechanism enables an autonomous length measurement. Beyond applications in production machines, opti- cal motion sensors can, for instance, monitor critical velocities, be applied for positioning tasks, or provi- de navigational information for automated guided vehicles.
