Why precise measurements are essential
The automotive industry is undergoing profound change: electromobility, alternative fuels and autonomous driving are placing new demands on research, development and quality assurance. At the same time, the demands on environmental standards, efficiency and safety are increasing.
LaVision provides optical high-precision measurements for the analysis of flow, combustion, spray behavior and material deformation – quickly, reliably and without mechanical intervention. In this way, development processes can be accelerated, emissions reduced and product quality sustainably increased.
LaVision - Your partner for optical high-precision measurements in the automotive industry
LaVision is the technology leader for optical measurement systems in research, development and industrial production. Our solutions provide detailed data on combustion processes, aerodynamic conditions, injection systems, material behaviour and the quality of critical components such as windscreens.
With state-of-the-art image processing, synchronized sensor technology and intelligent evaluation software, we enable leading OEMs and suppliers to gain deeper insights into their processes – for better products, safer vehicle systems and sustainable innovations.
Sharpening our view of the future - with optical precision for autonomous driving
Autonomous driving requires uncompromising visibility. Only when windscreens are of the highest optical quality and camera and sensor systems are reliably cleaned can safety-relevant driving functions work flawlessly – in any weather, in any situation. LaVision supplies certified test procedures and high-performance measurement solutions for this purpose – from glass qualification to climate testing in the wind tunnel.
