Laser displacement sensor is a kind of non-wire wound potentiometer with linear relationship between voltage output and axis rotation Angle or linear displacement, which is characterized by high precision, high life, high smoothness and high resolution. It can be used as position feedback, position detection, level adjustment, etc. Laser displacement sensors are suitable for long distance detection, and are used in industrial automation, transportation, steel, construction, docks and other applications where automatic distance displacement measurement and position control are required. So what should we pay attention to when using laser displacement sensors? The following is introduced by Shenzhen Liyi technology manufacturer:

Laser sensors (linear displacement sensors) are sensors that use laser technology for measurement. It consists of a laser, a laser detector and a measurement circuit. Laser sensor is a new type of measuring instrument, the use of laser with high directivity, high monochromism and high brightness characteristics, its advantages are to achieve non-contact long-distance measurement, fast speed, high precision, large range, anti-light, electrical interference ability.

Today, the laser displacement sensor is a precision measuring instrument that can measure displacement, thickness, vibration, distance, diameter and other precise geometric measurements. Because of its high measurement accuracy and non-contact measurement characteristics, laser displacement sensor is widely used in universities and research institutions, automotive industry, machinery manufacturing industry, aviation and military industry, metallurgy and material industry precision measurement and detection. Today, Shenzhen Liyi Technology manufacturer introduces the principle of laser displacement sensor laser triangulation:

Why do people like to use 3D visual inspection, because its biggest function is to replace the manual high-precision detection of product equipment and other defects, to prevent quality products from flowing into the market and thereby damaging the interests of consumers, its efficient, fast and accurate detection not only greatly reduces labor costs, but also effectively reduces the flow of unqualified products due to fatigue. Therefore, 3D visual inspection is applied to the internal and external inspection of auto parts and many products. So why do we all like to use 3D visual inspection? And listen to Li Yi Xiaobian for you

At present, the white light interferometer is one of the most accurate measuring instruments in the field of 3D. The white light interferometer is a hyperfine surface profile measuring instrument developed by the principle of optical interference. The illumination beam is divided into two beams by the semi-reflective semi-permeable spectroscope and projected onto the sample surface and the reference mirror surface respectively.

The spectral confocal displacement sensor passes a beam of white light (or multi-wavelength mixed light) through a small hole, and focuses different wavelengths onto the optical axis through the lens, dispersing to form a rainbow distribution band, shining on the sample, and some of the reflected light is reflected back. The light that is not illuminated at the intersection of the optical axis and the surface of the object passes through the spectroscopic part, and is illuminated around another small hole, which is blocked and cannot be illuminated to the spectral analyzer, and does not interfere with the measurement. The light shining at the intersection of the optical axis and the surface of the object passes through the splitter component and illuminates the spectral analyzer through the small hole. According to the wavelength calculation, the distance between the lens and the measured object can be obtained. Today, Xiaobian introduces the detection principle and thickness detection model of spectral confocal displacement sensor.
