In this work, we develop a new opto-acouto-fludic microsopic system, which employs a high-speed one-dimensional galvanometer scanner and an ultrafast pulse laser (600 kHz). The new system has achieved a high two-dimensional frame rate of up to 2500 Hz with a lateral resolution of 1.7 mu m and an axial resolution of 36 mu m at the imaging plane. To demonstrate the improved performance of the new system compared to our previous one, we carried out experiments to image the flowing droplets generated with T-junction and flow focusing configurations. We also successfully imaged dynamic migration of magneto particles subjected to non-uniform magnetic field in the microchannel. The results suggest that our new system has sufficient spatiotemporal resolutions to carry out studies for high throughput microfluidic applications.
