Abstract

As one of the interesting optical techniques for measurements of velocity, the spatial filtering method is treated briefly in this paper. We show theoretical analysis and calculation of spatial filtering velocimetry, and discuss two-dimensional measurements of velocity. About the data processing, we use A/D conversion and interface with a microcomputer, so that the data can be processed automatically by the microcomputer. It not only omits some complicated instruments, but also makes the measurement faster and more accurate. The preliminary experiment was performed and the experimental results show the usefulness of the present velocimeter for measurements of the velocity.
