Abstract
Some types of technique and system have been used in practical applications of Particle Image Velocimetry (PIV). PIV system composed with twin-YAG laser and a correlation camera is a typical one which can be applicable in the wide range of velocity. Its time resolution, normally, is limited at 15 Hz due to imaging technique. On the other hand, video PIV is useful for time series measurement of low speed flow, because of 60 Hz time resolution by using field images obtained by interlace scanning. In video PIV using interlace images, an interpolation technique is applied in order to obtain a full frame image, and it causes uncertainty and error of this method. In this report, an algorithm of video PIV without any interpolation is proposed and the results obtained are compared with ones by using interpolated images.
