Abstract

In this paper, a real-time measurement of liquid concentration changing in a Y-type microfluidic chip by digital holography is presented. In the experiments, the different concentrations of salt solution are injected into two channels of the Y-type microfluidic chip as a target object, and then the digital holograms related to the target solutions are recorded. The refractive index of the solution can be obtained from the reconstructed phase image. The experiment results show that the real-time changing of liquid concentration in microfluidic chip can be effectively measured by digital holographic microscopy.
