Linearity is simply the deviation range between the displacement of the object measured by the sensor and the actual displacement of the object. This indicator is useful when the measurement altitude difference is relatively large, and it is hoped to pay attention to the real absolute altitude difference.

TsingboPhotonics when measuring the repetition accuracy of the laser displacement sensor and the laser profile sensor, the industry practice method is adopted:

1. Use standard samples;

2. Take the average value of 4096 times on the reference distance as the value.

The relationship between the repetition accuracy and the accuracy of the actual industrial site is as follows:

1. Due to the influence of the surface gloss and color of the product, the accuracy will generally decrease;

2. The average number of industrial field measurements is generally less than 4096;

3. Experience shows that the actual accuracy is usually 2_10 times of the repetition accuracy, which is affected by many factors such as samples, site conditions and software algorithms.
