Triangulationhigh precision laser distance sensor in trigonometry and geometry, is a method of measuring the distance to a target by measuring the angle between the target point and known endpoints of a fixed baseline. It does not directly measure the distance to a specific location. When one side length and two observation angles are known, the observation target can be identified as the third point of a triangle.
This method is simple in principle and requires a small amount of data. It can measure various types of object surfaces, including mirrors, rough surfaces, transparent objects, etc., with a measurement range from micrometers to meters. However, it can only measure the height of a point or an object on a line on the object to be measured at a time. To achieve full-field measurement, the measurement equipment needs to be installed on a two-dimensional or one-dimensional scanning system. Triangulation also has wide applications in astronomy, such as measuring the distances between the Sun, the Moon, and other celestial bodies and the Earth.OEM laser distance measurement
