<title>New multiple-channel image plane holography realized by multiple reference beams</title>

Abstract

Based on the multiplicity and redundancy of holographic recording and reconstruction, the paper presents a new kind of multi-channel image-plane holography, which used the method of multiple reference beams in one exposure to record and give the object' s information in different field angles simultaneously. The construction principle of dual-reference-beam multiple-image- plane recording with the diffraction wave theory is also presented. As an example, a dual-reference-beam image-plane hologram is given. Image plane holography was noted for its colorfulness and low dependence of reconstruction. But the view field of usual image hologram was largely limited. The accessible research in multiple channel holography can only reconstruct object's image in a fixed directional single channel, which limited the visual range and collected object's information in multiple channels at the same time. So it is very worthful.
