There are many units and details about the laser displacement sensor. For example, it can be divided into an internal processing unit, a transmitting and returning unit, a receiving unit and an analysis unit of the laser receiver, etc. Because it can emit a large number of laser pulses per unit time, so In order to greatly reduce the processing time of the laser displacement sensor, multiple optimizations have been made on the sensor receiver in recent years, so that it can be completed in a short time even in long-distance detection.

1. Why use a laser displacement sensor?

The development trend of laser displacement sensors is extremely fast. In order to maintain the flatness of the glass, it is necessary to accurately control the temperature in a wider range. This is because if there is a temperature difference in the glass substrate, residual stress will be generated, resulting in The glass is deformed due to bending, or the glass is deformed during cutting, which affects the stability of the glass substrate, and may also be due to residual stress. Causes the phenomenon of light leakage in the LCD module. The domestic laser displacement sensor manufacturer claims that the stress will cause scars on the glass surface, and will also cause damage to the substrate.

2. What are the technical advantages of using a laser displacement sensor?

The flatness of transparent materials can be successfully measured by using the laser displacement sensor, which makes up for the deficiencies of the traditional laser displacement sensor in the measurement of transparent materials or specular reflection, and increases the new application field of the laser displacement sensor. The holographic sensor is based on a unique patented conoscopic holography technology, which is superior to existing standard distance measurement methods for various industrial applications. The sensor is reliable, accurate, and contains no moving parts. Compared with the standard trigonometry, there are two advantages of collinearity and low electronic noise dependence in the measurement system. Non-contact distance sensors for autofocus in laser marking, welding, drilling and cutting systems.

In addition, the physical and chemical applications of the laser displacement sensor can be analyzed from the perspective of its measurement distance and measurement speed. In addition to the measurement of the above two conventional quantities, the more important thing is the measurement of vibration. This kind of microscopic measurement quantity is usually used in various In high-tech industries, it is often necessary to measure physical quantities such as orientation while measuring vibration. For example, in the detection of various physical pipelines, or in the process of air pollution and prevention and control, laser displacement sensors need to be used.
