A method of reconstructing positive and negative images simultaneously from the same dc-removed coaxial Fourier hologram with the same reference pattern is presented. The simultaneous reconstruction is possible by making the polarization of the additional dc component of the signal beam perpendicular to the polarization of the reconstructed signal beam, in which separately detected s- and p-polarization components create contrast-reversed images. This method provides an aspect of designing dc-removed coaxial holographic storage systems for realizing optical noise reduction and less consumption of dynamic range of the recording medium.
本文提出了一种从具有相同参考图案的同一去直流同轴傅里叶全息图中同时重建正像和负像的方法。通过使信号光束的附加直流分量的偏振方向垂直于重建信号光束的偏振方向，可以实现同时重建，其中分别检测到的 s 偏振分量和 p 偏振分量创建对比度反转的图像。该方法提供了一种设计去直流同轴全息存储系统的方法，用于实现光学降噪和减少记录介质动态范围的消耗。
