In recent years, dual-channel images recording by polarization holography has been proposed. However, in conventional dual-channel images recording, an unchanged polarized reference wave is employed while signal waves have orthogonal polarization, which makes two holographic images can only be read out simultaneously. In this paper, we report polarization-controlled dual images recording within polarization holography written by orthogonal linear polarization waves. In this method, two polarization multiplexed holographic images could be sequentially readout by shifting the polarization state of reference wave based on null reconstruction effect(NRE) of linear polarization holography. NRE is an unique phenomena in polarization holography which means the diffraction efficiency goes down to zero when the hologram is reconstructed by orthogonal polarized reading wave. In this paper, we study polarization holography recorded by orthogonal linear waves and find that the NRE of orthogonal linear polarization holography can be achieved at large cross-angle of inside the polarization-sensitive media. The NRE of linear polarization holography is experimentally demonstrated by recording orthogonal linear polarization hologram in fabricated cubic material PQ/PMMA whose size is 10 mm ×10 mm ×15 mm. Based on the NRE of orthogonal linear polarization holography, polarization-controlled dual images recording is carried out. Two images encoded by orthogonal linear polarization waves are sequentially recorded in same position of cubic PQ/PMMA by orthogonal linear polarization holography. In reconstruction stage, The two holographic images are sequentially readout by shifting the polarization state of reference wave with negligible inter-channel crosstalk. The experimental results agree well with theoretical predictions. And this polarization-controlled dual images recording method has promising applications in optical storage, vector light field modulation and multi-functional optical devices.
