Abstract

An alternative method for determination of 3-D object fields is presented. The holographic multiplexing technique is employed in this method to record the multidirectional projections of the object field. The multiplexed hologram thus generated can be used to reconstruct the different directional projections of the studied field sequentially in the optical system. In addition, it provides series sets of projection data by means of an image sensing device for computer digital postprocessing. With the aid of a digital reconstructed image, the structure of the studied object field can be well determined. Illustrations of the recording and reconstructing systems as well as the algorithm adapted to reconstruct the field image digitally are given. Some preliminary results are also provided.
