Understanding Measurement Uncertainty in Video Measurement System (VMS) Inspection
When inspecting a precision component, the measured dimension is often treated as an exact value. In reality, every measurement carries a degree of uncertainty that must be considered when determining whether a part truly meets its tolerance requirements. Understanding measurement uncertainty is therefore essential for reliable dimensional inspection. This article explores the concept of measurement […]
The Science Behind Non-Contact Optical Measurement in Video Measurement Systems (VMS)
Non-contact optical measurement refers to the acquisition of dimensional and geometric data without physically touching the measured component. Instead of mechanical probes, these systems rely on controlled illumination, precision optics, and digital imaging to extract measurable information from reflected or transmitted light. As manufacturing tolerances continue to tighten and component geometries become increasingly intricate, traditional […]
