Laser triangulation

Laser triangulation is a non-contact optical measurement technique used to measure surfaces. In laser triangulation, a laser beam is directed onto the surface to be measured and received by a sensor. By analyzing the reflected laser beam, the distance between the sensor and the surface is measured.

The principle of laser triangulation is based on triangulation, a geometric principle that determines the distance between two points by measuring the angles and side lengths of a triangle. In laser triangulation, the light emitted by the laser is directed onto the surface and reflected back. The reflected light is collected by the sensor, which measures the angle between the laser beam and the reflected beam. Based on this information, the distance between the sensor and the surface can be calculated.

Laser triangulation is used in various applications such as product quality control, measurement of components and detection of surface defects. It can also be used in robotics to measure the position of tools or track the movement of robots.

Another advantage of laser triangulation is that it is fast and precise, and does not require direct contact with the surface to be measured. This makes it an ideal method for measuring sensitive surfaces or for applications where direct contact needs to be avoided.

Overall, laser triangulation is an important technology for the precise measurement of surfaces in many different industries. It provides fast, precise, and non-contact measurements that can be used for a variety of applications.
