Abstract
This paper evaluates the performance of a digital holographic particle measurement using deconvolution for measuring a three-dimensional flow. In digital holography, the measurement accuracy in depth is reduced because a reconstructed particle image is elongated along depth direction. In order to overcome this difficulty, a deconvolution technique is employed the suppressing the particle image elongation. We apply this digital holographic particle measurement using deconvolution for the detection of particle displacement. In numerical simulation, the measurement accuracies with and without deconvolution technique are evaluated for the model of cubic cavity flow. It is shown that the measurement accuracy is improved by the present method with deconvolution technique.
