1.Wide range of measurement

LGD and LSG laser scanning diameter gauges can realize accurate measurement within the range of measurement regardless of whether the object under test shakes or swings. Given completely non-contact measurement without the need of a positioning bracket, there will be no scratches or squeezing of the object under test which may affect product quality and increase the error of measurement.

How to test dynamic accuracy of a laser scanning diameter gauge: 

Take an object under test and move/shake it at each of the points 1, 2, 3, 4, 5, 6, 7, 8 and 9 in the measurement area as shown in the figure below.

1) Observe how the measurement of the same object under test changes at different points.

2) Simulate the production site and observe how the measurement changes when the object under test shakes or swings. 

3) The smaller the changes of measurements in the above two steps, the higher the dynamic accuracy of the diameter gauge.



2. High accuracy and stability of measurement

Imported high-speed micro-motor (high scanning frequency), military-grade process laser (high collimation), design and processing of the latest aspheric optical system, and optimized specific edge detection algorithm are adopted. The diameter gauge can realize a scanning frequency up to 2400 Times/S (per axis) and accurate identification of the edges of the object under test, ensuring that more single scanning values of the object under test are obtained in one measurement cycle. High-precision single-cycle accurate data collection can reflect the dimensional changes and surface defects. The particles, paint bumps, bubbles, blisters and other surface defects of the products can be detected within a very small scanning interval. The defects larger than the minimum measurement interval can be accurately detected. For the measurement of flat objects in particular, the optimized edge algorithm is combined to more accurately measure their width and thickness, which is not available in traditional methods of measurement or measuring instruments with a low scanning frequency.

The type and size can be measured based on lumps and necks in the 

measurement area

Corrugation &jag detection

With a high scanning frequency, the peak and trough values can be accurately detected and a large number of scanning values can be obtained within a certain measurement interval, so that the maximum and minimum values can be accurately calculated.
