Abstract

The invention relates to a method for calculating a gross thickness and mass proportions of all single-color materials at any point or in any area based on a color light-transmitting image of a colormixture material; and a series of experiments are designed to verify the high adaptability of the algorithm in the common transparent high polymer material. Therefore, an analysis and calculation problem of the mass proportions and the mixing uniformity of all color materials in the color mixture material is solved.

Description

technical field [0001] The present invention relates to a method for testing and analyzing the thickness and mass ratio of each color material in a planar color-mixing material, in particular to a method for analyzing the mixing ratio of each color material at any point based on the light-transmitting image of the color-mixing material. Background technique [0002] The thickness or surface density distribution of each single-color material in the color-mixing material is an important variable that characterizes the structure and quality (or thickness) uniformity of the color-mixing material, and is also an important basis for studying the thickness and proportion of each color material at any point in the color-mixing material. Lambert's law based on unidirectional absorption is widely used in the measurement of the thickness of light-transmitting materials. For example, the ultraviolet spectrophotometer uses the principle of Lambert's law to calculate the thickness of the ...
