摘要
When a pinhole array is employed as a redundancy means in recording a redundant Fraunhofer hologram, such as a holographically prerecorded motion picture, a moving noise is normally present in the reconstructed image when the hologram is moved during playback. The effect of this moving noise is eliminated by situating the hologram recording medium at or in the immediate vicinity of the image plane of the pinhole array during the recording of the hologram. By recording the hologram in this manner, flicker-type noise is also improved.
