The spectral confocal displacement sensor emits a beam of high density and wide spectral light through the color laser light source.

The VisionCon2021 VisionSystem Design conference, co-sponsored by ACTInternational and VisionSystemsDesignChina, will be held in Shanghai on November 19. The device manufacturers, system integrators, enterprise users and scientific research institutions in the machine vision industry chain will be invited to gather together to discuss the development opportunities of the latest machine vision technology in the manufacturing industry!

In recent years, the application field continues to expand, more and more innovative technology has been applied to the sensor

Nowadays, with the rapid development of industry, the demand for precision measurement technology is getting higher and higher, displacement measurement technology as the basis of geometric precision measurement, not only requires ultra-high measurement accuracy, but also needs a wide range of adaptability to the environment and materials, and gradually tends to real-time, non-destructive testing.

Spectral confocal measurement technology analyzes the focusing position of different wavelengths of light on a specific surface to carry out high-precision dimensional measurement and micro-morphology analysis. Surface roughness is a concept used to express the micro-geometric error of the surface of a part. The error size of the micro-geometric shape is expressed in microns.

The feasibility of using the spectral confocal displacement sensor to measure the thickness of the transparent material parallel plate is analyzed in detail, and the corresponding compensation method is given.
