The possibilities for integration into existing data acquisition hardware and the low additional acquisition costs allow the current status to be used directly in applications in research and industry. Based on the achieved results, further steps of the measurement can be integrated into the system, but also existing methods can be improved and validated on new measurement applications. All in all, this system offers a new kind of interaction and assistance during and before the measurement, which does not exist in this form at this time. In addition, the measurement
