Abstract
A double-exposure phase-shifting holography applied to particle velocimetry is proposed and analyzed theoretically in this paper. The background noise of the reconstructed particle image can be eliminated by means of the proposed holography so that the SNR of the image is increased significantly, which makes it easy for a computer to automatically analyze the reconstructed particle image. The experimental results of a simulated velocity field are given.
