Shortwave infrared (SWIR) imaging is quietly earning a growing place in industrial machine vision for quality inspection. SWIR imagers, sometimes also referred to as NIR imagers, can see objects and events that vision and thermal cameras cannot.

Test and measurement equipment (T&ME) must be periodically calibrated to ensure it’s operating within its specified parameters.

How many dimensional data points are enough to accurately describe a part feature? The key to answering this question is understanding the stability of the manufacturing process.

Coordinate measuring machines gather data by means of a probe or sensor. Conventional CMMs equipped with touch-trigger probes can use a stitch-scanning method to record point streams from part surfaces.
