| Abstract: | A new technique for 3 Dimensional image velocimetry is presented. Based on circular velocity bias method, the three components of partical velocity can be simultaneously determined by a single camera. Theoretical analysis and typical experimental measurement for several movements are given. They show that CVB is feasible and reliable. |
