Abstract

The effect of scene motion on a hologram is a spatial modulation of the recorded fringe contrast. This in turn causes a spatial amplitude modulation of the reconstructed wavefront which blurs the reconstructed image in much the way it would be blurred by a normal photograph of equal exposure time. The modulation also reduces the brightness of the reconstructed image.

The theoretical analysis predicts the effect on the hologram of a moving single-point scene and experimental results are shown to verify the theory for radial and transverse motions.

Several cases in which large amounts of scene motion may be allowed are discussed and experimental results showing blurred reconstructed images are given for one such case.

It is shown that the integrated image of a moving scene obtained using holographic recording will in general have a different energy distribution than an image recorded in an image plane of a lens.
