Optical metrology is an established technology in the coordinate measurement community, with a growing impact on the specialized field of gear metrology. The idea of a contactless and thus fast technology for quality control is promising. Nevertheless, every new technology raises questions: How to use this technology and what are meaningful use cases? Looking deeply into the field of optics evokes even more questions: What kind of optical technologies do exist, what is the adequate technology for your application and do I need a special sample preparation? This paper provides a quick overview about optical metrology for gear analysis and provides some field results of optical gear measurements. The results are focused on gears for automotive applications, especially for the expanding area of electric drivelines.
