Abstract

The invention discloses a light source normalization processing method of a spectral confocal measurement system, which is to calculate the spectral intensity distribution of the light source by collecting the signal of the spectral confocal light source, and convert it into a normalization coefficient. The present invention can normalize the collected measured target signals in the normal measurement process to solve the problem of poor spectral uniformity of the light source, correct the error caused by the uniformity of the light source, and measure other optical devices in the system Error, so that the measurement accuracy and stability of the spectral confocal displacement sensor can be improved.

Description

technical field [0001] The invention relates to the field of non-contact measurement, in particular to a light source normalization processing method of a spectral confocal measurement system. Background technique [0002] The spectral confocal displacement sensor is a new type of non-contact photoelectric displacement sensor with ultra-high precision and ultra-high stability. This technology is recognized globally as an accurate and reliable non-contact distance and thickness measurement technology, and is one of the few non-contact three-dimensional measurement technologies recommended by the ISO25178 international standard. [0003] Spectral confocal technology uses the principle of confocal microscopy to establish the correspondence between the focal distance and the wavelength through the dispersion frequency selective optical system, and then uses the spectrometer to decode the corresponding wavelength information to obtain the corresponding displacement information, a...
