| Abstract: | A two-dimensional vector velocimeter is proposed on the basis of the time-varying spatial filtering method using a rotating disk with two transmission gratings. The filtering characteristics of the spatial filter used in the velocimeter were studied theoretically. A preliminary experiment was performed to measure the velocity vector of a rotating random pattern. The experimental results show the usefulness of the present velocimeter for measurements of the velocity. |
