Abstract
New PTV measurement using a Fourier-Transform phase correlation method is attempted on the experimental flows showing a 2-D circular cylinder wake. To make a good use of the qualities of this phase correlation method, the image templates for pattern matching are not described by the original particle dots, but by single polygons connecting all the particles in each template, followed by 2-D normal FFT and phase-component inverse FFT processes. The results obtained are not so revo-lutionary when compared to ordinary direct correlation methods, but there exists apparent improvement in the rotating flow regions.
