Automatic Video Measuring Machine Optical System Analysis: Lens, Imaging, and Lighting
The performance of an automatic video measuring machine depends on three key factors: true optical imaging, clear image quality, and stable edge detection. These are achieved through the integration of a dual-magnification telecentric lens, a high-resolution CCD camera, and an adjustable lighting system.

Where Do Profile Projector Measurement Errors Come From: Principles and On-Site Factors
In precision manufacturing, profile projectors are widely used for dimensional inspection and contour observation. Compared to contact measurement devices, they are intuitive and flexible. However, users often notice that repeated measurements of the same workpiece can vary, and results may differ between operators.

The Impact of Optical Magnification on Measurement Uncertainty in Video Measuring Machines Magnification Is Not Just Visual; It’s a Measurement Basis
In optical measuring systems, magnification is often misunderstood as simply “making the image look bigger.” In practice, whether it is a Video Measuring Machine or a visual measuring system, the key factor affecting measurement results is how the optical system maps the physical geometry of a workpiece onto the image sensor for sampling, not the display size. A video measuring machine or any optical measuring device derives measurement capability from proper imaging and sampling conditions, rather than visual appearance. Even if the image is digitally zoomed on the display, measurement uncertainty will not improve if the optical sampling conditions are insufficient. High-end VMMs are therefore designed with optical magnification as a core parameter.

Analysis of the Impact of Mechanical Structure on the Long-Term Stability of Video Measuring Machines
In the field of precision dimensional inspection, a Video Measuring Machine (VMM), as a typical non-contact optical measuring device, relies not only on its optical system and measurement software, but also heavily on the long-term stability of its mechanical structure. In practical applications, even when Video Measuring Machines share identical optical configurations and measurement principles, noticeable differences in measurement consistency and repeatability can still appear after years of continuous use. Such differences are rarely caused by short-term calibration issues, but rather by the cumulative effects of mechanical structural behavior over time.
