We present a microfluidic terrace based on a fiber-visual three-way Mach-Zehnder interferometer (MZI), proposed to measurement of the refractive index (RI) of liquids and description of suspended jug particles (cylinders) simultaneously. The calculation principle is established low coherence interferometry, place the maximum position of the interferogram Gaussian envelope depends on the ocular path difference (OPD) betwixt the measuring and the remark arm of the MZI. An algorithm was developed for manipulative the refractive index of liquids and mirror particles, as well as for judgment the particle width from the raw photodetector signals. The physical atom diameter is planned from the measured particle transportation time while passing through the test beam. We erect very good understanding between the experimental results and the article data on the checked liquids refractive index and dimensions and refractive index of postponed particles. The veracity of the refractive index measurement was about 1 %, mainly contingent upon the accuracy of position review of the mechanical scanner. The littlest sample volume maybe as small as 1 µl is capable of weighing the refractive index of different fluids and gases and their suspensions simultaneously. The projected method is appealing for label-free biological, biochemical and chemical grasping because of allure high sensitivity and veracity and self-calibrating feature.
