In this article, the implementation of low-coherence interferometer with signal processing in time domain for sugar content determination in aqueous solution is presented. The elaborated measurement set-up was tested with the use of synthesized source made of two low-coherence sources. The use of two sources with dedicated parameters enabled to obtain a proper metrological parameters of the measurement system. The elaborated low-coherence system enables to measure sugar content in aqueous solution with correlation coefficient R2 equal to 1, and the relative error of measurement in the range of ± 5,8%.
