The application of laser sensors in measuring tire tread depth is based on its high precision and fast response characteristics. This technology not only improves measurement efficiency, but also ensures the accuracy of data, providing reliable technical support for tire safety monitoring and maintenance.

The working principle of laser sensors is mainly based on the principle of laser triangulation. When the laser beam is emitted to the tire surface, it forms a light spot on the tire surface, and the reflected light is received by the detector through the optical system in the sensor. The system accurately measures the distance between the sensor and the tire surface by calculating the angle and distance between the emitted light and the reflected light. Due to the high precision and high resolution of laser sensors, they can capture tiny surface changes and provide accurate depth measurement.

In tire depth measurement, laser sensors can scan the pattern on the tire surface non-contactly. By continuously measuring the different distances between the sensor and the tread, the system can calculate the depth and wear of the tread. The advantage of this method is that it can quickly and accurately cover a large area of ​​the tire surface, and obtain reliable data even when the irregularity and roughness of the tire surface are large.

In addition, laser sensors are also suitable for online real-time monitoring. This means that tire depth can be detected instantly on the tire production line or during vehicle maintenance without removing the tire from the vehicle or interrupting the production process. This real-time monitoring not only improves production efficiency, but also makes tire wear detection more convenient and economical.

The improvements in size, accuracy and ease of use of the new laser sensors have significantly improved their efficiency and accuracy in tire detection. These sensors use advanced laser technology to achieve non-contact long-distance measurement, providing an efficient and accurate solution for tire depth detection.
