Circular dynamic stereoscopy (CDS) has special advantages as it enables 3-D measurements using a single CCD camera without any cumbersome settings. Annular streaks are recorded using this system and the size of the annular streaks directly relates to the depth/distance from the CCD camera. That is, the size of annular streaks is inversely proportional to the depth/distance from the CCD camera and therefore three-dimensional information can be measured automatically by image processing techniques. In this paper, PIV system using circular dynamic stereoscopy is introduced. Experimental results demonstrate the feasibility of our method.
