A Comparison of OGP® SmartScope® Sensors

A fundamental lack of research into the performance capabilities of the various sensors available to OGP SmartScope measurement system operators makes for a steep learning curve and increased difficulty in selecting the right sensor for the job. 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.
