Description
Technical field
The present invention relates to liquid coloration detection technique fields, in particular to a kind of liquid chroma detection method and dress
It sets.
Background technology
As the important attribute of substance, color is indicated jointly by brightness and coloration, and it does not include brightness that coloration, which is then,
The property of color inside, what it reflected is the tone and saturation degree of color.With China's industrial expansion, coloration has become
Evaluate the important indicator of product quality.Whether liquid coloration containing harmful chemical plays indicative function, therefore liquid to liquid
Body colorimetric detection plays an important role in environmental quality monitoring.Commonly colour measurement method includes：Visual method, photoelectric integration
Method and spectra photometric method.Visual method is earliest for color measuring, this method largely to rely on the subjectivity of coloration observer
Judge, therefore color detection power and measurement accuracy are poor.Photoelectric integral method does not measure the psychrometric colour specification of a certain wavelength instead of,
Some range of wavelengths is measured, this method can only accurately measure the aberration in two color sources, cannot accurately measure three thorns in color source
Swash value and chromaticity coordinate.
The common sensor for measuring coloration using spectra photometric method has RGB sensors and XYZ sensors.RGB sensors are only
There are three channel, to the reduction degree error of realistic colour between 10-15%.And RGB sensors are only under particular light
After being calibrated, point-device color dot analysis result can be just provided under the conditions of that particular light.But between instrument
Light source consistency be it is difficult to ensure that, especially to cost than more sensitive product, and measurement result is also merely representative of
Currently measuring the chromaticity coordinate under illumination.The advantage of XYZ sensors is that euchroic can be provided under most of illumination conditions
The identification of color dot, only 1%~5% error, XYZ sensors can be in the manufactures and test of chip as one be calibrated
Point, one by one checking process of the luminaire manufacturers for different light sources is eliminated, it can effectively save time and cost.

Relate to wave filter technology.Interference filter can be directly deposited on wafer, and can simulate the spectral response characteristic of human eye.TCS3430
Filter tool there are five channel, including the channel X, Y, Z and two infrared channels.
In practical applications, due to being influenced by mains fluctuations and circuit inner noise, TCS3430 singles are surveyed
The XYZ psychrometric colour specifications that amount colourless transparent solution obtains are inaccurate, using maximum Likelihood, according to colourless transparent solution
M group XYZ colour stimulus measured values, corresponding to colourless transparent solution XYZ colour stimulus measures true value and estimates, obtain colourless
The corresponding XYZ colour stimulus of bright solution measures true value.The XYZ colour stimulus of colourless transparent solution measures true valueWith M times
Relationship between XYZ colour stimulus measured values can be expressed with following formula：

Step S220：Based on preset computation rule and the M groups XYZ colour stimulus measured value and the N groups XYZ colour stimulus
Measured value obtains chromaticity coordinate of the testing liquid under preset standard..
Since TCS3430 sensors itself are there are converted deviation, sample the XYZ colour stimulus being calculated and measure true value and phase
The relationship of colour stimulus actual value is answered to can be represented by the formula：
Wherein,The XYZ colour stimulus of the liquid for certain color being calculated for sensor sample measures true
Value, (X, Y, Z) are the true XYZ psychrometric colour specifications of corresponding light component, m, k1,k2For scale factor.According to CIE-1931XYZ color specification systems
System, in order to determine the chromaticity coordinate of certain colorIt needs first to determine scale factor k1,k2
Size.
