Laser displacement sensor is a new breakthrough point for the detection of different parameters such as displacement, thickness and height, and many people are using laser displacement sensor video preparation to deeply understand its measurement methods and application functions. The triangulation method and laser echo analysis method are the more commonly used measurement methods of displacement sensors. Now what are the differences between triangulation method and laser echo analysis method for you to further analyze:

The differences between laser displacement sensor triangulation and laser echo analysis are as follows:

1. The distance suitable for measurement is different

There is a great difference between the triangulation method of laser displacement sensor and the laser echo analysis method in measuring the distance of objects. Generally speaking, the triangulation method can reflect the light to the surface of the object through the lens, so it is more suitable for the measurement of short distance parameters; The laser echo analysis method is more suitable for the measurement of long-distance parameters, because the distance of the echo is longer than the wavelength of visible red light.

2. The working principle on which the measurement is based varies greatly

The triangulation method with high application rate of laser displacement sensor refers to the use of visible red laser to shine at the object to be measured, and then reflect the laser through the object and receive by the receiver lens. For example, CCD linear camera is to obtain light points through different angles to detect the distance between the laser and the camera; The laser echo analysis method is mainly based on the time required for the transmitted pulse to meet the obstacle and then measure it.

3. Measurement accuracy is different

According to the feedback of many users, the measurement accuracy of laser displacement sensor triangulation method and laser echo analysis method is different. Many people have found that the triangulation method has higher measurement accuracy in the machining and loading and unloading assembly operations, and the laser echo analysis method has a longer distance, so its measurement accuracy is slightly lower than the accuracy of triangulation.

According to the survey feedback shows that the application rate of laser displacement sensor in the market is increasing year by year, and the position of those laser displacement sensor manufacturers is also rising. According to these manufacturers, the difference between the triangulation method and the laser echo analysis method of the laser displacement sensor is not only manifested in the different measurement distances, but also in the different principles based on the measurement and the different accuracy levels of the measurement.
