摘要：
A video imaging method for measuring motion by analyzing the optical flow of the video image sequence using spatial-temporal Fourier transform is presented. The principle of measuring motion in the spatial-temporal Fourier domain is given and its performance is studied by computer simulation. The feasibility of this technique in measuring the flow speed of a highly turbid demixing binary liquid mixture where conventional optical methods (such as PIV and LDA) cannot be used is demonstrated. © 1995 American Institute of Physics.
