Abstract
Based on the newly developed tensor holography theory, the null reconstruction in orthogonal elliptical polarization holography is reported. In the recording stage, the information is stored in the recording material by two orthogonal elliptical polarization waves. In the reconstructing stage, the variation of the power of reconstructed wave with the polarization state of reading wave is studied. Then the null reconstruction, the reconstructed wave being identical to zero, is observed when the reading wave is the non-orthogonal reference wave of recording stage. However, in those previously reported experiments, when and only when the recording material is illuminated by the orthogonal reference wave, the null reconstruction could be observed. Thus, our result is very different from the previously reported results and would change the perspective on the null reconstruction. Based on the tensor theory, we analyze the condition for null reconstruction in orthogonal polarization holography. For the null reconstruction in orthogonal linear polarization holography, the reading wave should be the orthogonal reference wave. However, for the null reconstructions in orthogonal circular and elliptical polarization holography, the reading wave may be the non-orthogonal reference wave. We think the result may enlarge our knowledge about the null reconstruction.
