The velocity measurement of cylinder flow is conducted using PIV technique. We use a motorized displacement stage to drive both the circular cylinder and video recorder. The aluminum cylinder with diameter of 6 mm and length of 38 mm is suspended in a glass tank filled with water, while the video recorder is also attached to the displacement stage to move synchronously with the cylinder. A beam of sectorial helium-neon laser irradiates the cylinder vertically from the downstream. To avoid severe reflection of laser, the cylinder has a matte finish all over its surface.
