Abstract
In this paper, we show theoretical analysis and calculation of spatial-filtering method for measurement of 2D vector velocity. About the data processing, we used A/D conversion and interfaced with a microcomputer, so that the data can be processed automatically by the microcomputer. The preliminary experiment was performed and the experimental results show the usefulness of the proposed method.
