Abstract

The invention provides a color confocal displacement sensor, and belongs to the field of displacement sensors, the color confocal displacement sensor comprises a light source assembly and an incident optical fiber, the light source assembly comprises a blue light LED chip, and a collimator, a fluorescent lens and a coupling lens which are sequentially arranged on the blue light LED chip, the incident optical fiber is aligned with the coupling lens; the fluorescent lens is borosilicate glass on which yellow and / or red fluorescent powder is uniformly dispersed; by arranging the borosilicate glass lens containing the yellow and / or red fluorescent powder, the consistency of the LED light source is improved, meanwhile, the blue chip further excites the yellow / red fluorescent powder, the yellow / red light is increased, and the problems of incomplete spectrum and uneven light intensity caused by color shift are solved.

Description

technical field [0001] The invention relates to the field of displacement sensor devices, in particular to a color confocal displacement sensor and a measurement method. Background technique [0002] Color confocal displacement sensor, also known as spectral confocal sensor and dispersion confocal displacement sensor, uses a special color-coded lens to generate axial dispersion output of visible light, and analyzes the confocal return light wave signal through a spectral analyzer, and finally passes through The measured value of workpiece displacement is calculated from the conversion curve of wavelength and displacement; the principle is: a beam of polychromatic light (white) with a wide spectrum is emitted from the light source, and spectral dispersion occurs through the dispersion lens to form monochromatic light of different wavelengths. All correspond to a distance value to the measured object. The measurement light hits the surface of the object and is reflected back....
