Chromatometer matching method, colorimeter and colorimeter correction method and system

Abstract

The invention provides a colorimeter matching method, a colorimeter and a colorimeter correction method and system, and the colorimeter matching method comprises the steps: obtaining a light passing core diameter of an optical fiber input end, determining the opening angle of the optical fiber input end based on the light passing core diameter of the optical fiber input end, and determining a field angle of a lens based on the opening angle of the optical fiber input end; controlling target light emitted by a to-be-measured area to enter the lens at a field angle and then enter the input end of the optical fiber at a flare angle, so that the target light is emitted from the output end of the optical fiber; and controlling the target light emitted from the output end of the optical fiber toenter the spectrograph, and matching the end face contour of the output end of the optical fiber with the slit contour of the receiving end of the spectrograph. According to the invention, the problem of low measurement efficiency caused by poor light receiving capability of a colorimeter in the prior art is solved.

Description

technical field [0001] The invention relates to the field of colorimeters, in particular to a colorimeter matching method, a colorimeter, a colorimeter calibration method and a system. Background technique [0002] With the gradual improvement of the quality evaluation system of color displays, lighting sources and other light-emitting products, it is more and more important to accurately measure the color and brightness of displays, etc., and the color measurement is mainly carried out by tri-stimulus colorimeters. A colorimeter is a laboratory instrument that measures or specifies color by comparison with synthetic pigments. A typical colorimeter has a standard light source, three colored filters, photocells, and a standard reflective panel. More advanced colorimeters use photocells and electronic circuits instead of human eyes as receptors, thus speeding up The result is obtained. The result of colorimeter detection is called chromaticity (CHROMATICITY). [0003] The w...
