Abstract

In this paper, a method to measure the flow speed based on microfluidic chip by digital holography in real-time is demonstrated experimentally. The injection pressure of microfluidic device is changed to create different flow rate in microfluidic channels. On this basis, the phase distributions within the microfluidic channels can be reconstructed by using digital holographic microscopy, and then flow rate can be obtain by measuring the phase distributions of cross section. The experiment results show that digital holographic phase image is an effective and real-time detection means for the characteristic parameters of micro-fluid such as flow rate and injection pressure. In addition, the chip calibration is made to ensure the validity of the experimental results.
