Optical measurement systems: advancement of superior test and measurement
Conventional measuring processes are becoming obsolete as they do not offer the required accuracy, are prone to errors and time-intensive. As opposed to that, optical sensor technology and laser-based test and measurement systems are faster while providing more accuracy and flexibility—and conserve energy.
Today’s automated manufacturing processes have become so fast that they can no longer be ascertained by the human eye. Conventional measuring processes do not support this speed, creating a demand for an alternative to mechanical methods.
Optical measurement systems: groundbreaking future-ready control methods
However, the use of optical test and measurement systems is no longer limited to industrial production processes. The speed, flexibility and precision of optical sensors is successfully used in various application areas outside of industrial manufacturing processes as well:
In monitoring applications for industrial production, optoelectronic processes have become essential: As opposed to conventional methods, these high-precision measuring processes are capable of lowering costs without compromising quality while enabling ecologically sustainable operations.
Architecture and design utilize the precision of laser-based measuring techniques to ascertain areas in order to optimize shapes or to achieve maximum precision in reverse engineering (making precise copies of a given object).
Criminalistics uses laser scanning for measuring and mapping crime scenes to create 3D models, enabling contactless search for evidence through measuring probes and hence avoiding compromised traces or pieces of evidence.
In forensics, stripe light projection is used as a measuring and testing system enabling precise spatial and dimensional reconstruction as well as digital reproduction of injuries.
Various natural sciences use optical analytical methods due to their excellent measuring capabilities for fast mapping and precise analysis of surfaces and motions.
Optical sensors and laser-based test and measurement systems have proven to be game changers in this scenario. Due to their superior measuring speed, they enable more efficient manufacturing methods that would not have been possible using conventional methods. This cost and energy saving technique benefits both companies and the environment.
Optical sensors are also integrated in agriculture applications to achieve an ideal ratio of sustainability and efficiency. Farmer Stephan Nunner uses them for fertilizing and tilling fields; in the following video he explains why he sees no alternative to optical processes:
Optical sensor systems and laser-based test and measurement systems have evolved into indispensable instruments in various fields. The latest developments in research and production indicate an ongoing expansion of application areas for optical test and measurement systems.
