Faithful reconstruction in polarization holography suitable for high-speed recording and reconstructing.

Abstract

We report on faithful reconstruction in polarization holography independent of the exposure time and the reading wave that is suitable for high-speed recording and reconstructing. Faithful reconstruction, the reconstructed wave being identical to the signal wave, is the basis of the application of polarization holography, which may be applied in many fields. Unfortunately, in many cases, faithful reconstruction depends on the exposure time and the reading wave when phenanthrenequinone-doped polymethyl methacrylate is used as the recording material, and then it is not easy to obtain faithful reconstruction. This limits its application in the field of high-speed recording and reconstructing. Directed by the newly developed tensor polarization holography theory, we report on faithful reconstruction breaking through these limitations. In the recording stage, the signal and reference waves are s- and p- polarized, respectively. In the reconstructing stage, the reading wave is arbitrarily polarized. More importantly, the obtained faithful reconstruction has nothing to do with exposure time and it is time saving. The reported faithful reconstruction would bring great convenience and is suitable for high-speed recording and reconstructing.
