    We have developed a simple method for measuring surface flow velocity inside a microfluidic channel. Tracking the refractive index boundary in the flow channel gave the flow velocity. The refractive index boundary was measured by surface plasmon resonance (SPR), thus our method gave both the physical flow condition and biological interaction information in a single sample run. In our previous attempt, we required the shape of the boundary to be predefined for tracking. In this report, we introduce a 2D Fourier transform based algorithm where no predefined shape is required for tracking, and we test its capability with a milk sample.
