Abstract
The multiple-exposure method in holographic interferometry is analysed on the basis of the general theory of fringe formation. The formula for determining the localization position is derived. Effects of the aperture of the observing optical system on the visibility and fringe shape are found to differ somewhat from the double-exposure case. The general results of the analysis of multiple exposure are applied to in-plane rotation of a disc and supported by its experiments. As a practical application, flow velocity distribution is visualized and some merits of such an application are suggested in consideration of the general properties of multiple-exposure holography.
