This research compared three typical sensors (video, touch probe, laser probe) and established a comparative performance baseline. The results indicate (with 99% confidence) significant differences within the controlled variable settings for the touch probe and video sensors – the video sensor performs best when using the ring light at 25% subject reflectivity and the larger touch probe styli outperform the smaller models. Although a single best sensor has not been identified in a global comparison, a subset of these which includes the laser, the thicker touch probe styli, and the ring light at 25% subject reflectivity, clearly outperforms the remaining devices.}, month = {1}, keywords = {metrology,quality,quality control,research}, issn = {2166-0123}, publisher={The Association of Technology, Management, and Applied Engineering and Iowa State University Digital Press}, journal = {Journal of Industrial Technology} }
