he advantages of spectral confocal principle (fiber coaxial displacement sensor/color laser displacement meter), friends who want to know can follow Shenzhen Limeter fiber coaxial displacement sensor manufacturers to see:

Many people do not know how to measure the spectral confocal sensor? Today, the spectrometer spectral confocal manufacturers will simply tell you:

Is it true that spectral confocal method does not require any surface? A beam of a wide spectrum of polychromatic light (white) is emitted from the light source, spectral dispersion occurs through the dispersion lens, and a single color of light of different wavelengths is formed in the range. The focus of each wavelength corresponds to a distance value. The measured light is reflected back to the surface of the object, and only the single-color light that meets the confocal condition can be sensed by the spectrometer through the hole.

The ultimate goal of spectral information processing is to obtain the peak wavelength. However, the internal return light of the fiber coupler, the uneven distribution of the light intensity of the light source, the different response degree of the CCD to different wavelengths of light, and the system noise will affect the system. All of them affect the location of spectral peak. It is necessary to pre-process and then extract the peak wavelength with appropriate algorithm. Below, Shenzhen Liyi spectral confocal manufacturers will talk to you about how to deal with the data of spectral confocal sensor signals?

As we all know, natural sunlight belongs to white light. White light is not pure light, but is made up of many monochromatic light. The wavelength of visible light from the human eye ranges from 400 nanometers (blue light) to 700 nanometers (red light). Light may have angular deviations when propagating in different media, but under actual white light irradiation, single-line light will have multiple refractions in different media.

In fact, in order to ensure the accuracy of every measurement result, almost all measuring equipment or systems need to be calibrated before use. Although measuring equipment and systems undergo a rigorous calibration process before leaving the factory, it is not permanent.
