Recently, optoelectronic methods measurement and control are successfully applied for quantitative and qualitative analysis substances and materials. High precision and sensitivity, economy and safety are their advantages in compared with other physico-chemical analysis methods. The essence of the optoelectronic analysis method that any substance reflects or absorbs, or emits light.Moreover, in depending on the chemical composition of the substance and quantitative ratio of components its elements changes in intensity light absorption, angle of reflection and others
light interaction characteristics radiation and matter.
