Image of fiber interference pattern, which is seen in polarized light of microscope, is analyzed thought the instrumentality of program. Uncertainty for four factors, which influence on the scheme of color limits dispensing is calculated. The factors, which negatively influence on final result of calculations, are developed according to the results of uncertainties analysis. An algorithm of fiber image processing, which gives an opportunity to reduce influence of negative factors, is suggested.
