A thinned Si substrate is proven to have a higher photocurrent which is suitable for 2D chemical imaging in this study. The operation conditions of bias voltage, pixel resolution and pixel per second was investigated to evaluate the performance of 2D dynamic imaging of the droplets distribution in the microfluidics. Images of merging pH solutions and oil was clearly obtained in the self-designed microfluidics for future applications of chemical or bio-reaction droplet.
