摘要:

我们提出的利用虚会聚光的无随机相位全息方法,可以在没有随机相位的辅助下获得超过全息图尺寸的大再现像。在振幅和相位全息图(相息图)中,重建图像具有低散斑噪声;然而,在低分辨率全息图中,与原始图像相比,我们获得了劣化的图像质量。我们提出了一个迭代随机无相位方法与虚拟收敛光来解决这个问题。

英文摘要:

Our proposed method of random phase-free holography using virtual convergence light can obtain large reconstructed images exceeding the size of the hologram, without the assistance of random phase. The reconstructed images have low-speckle noise in the amplitude and phase-only holograms (kinoforms); however, in low-resolution holograms, we obtain a degraded image quality compared to the original image. We propose an iterative random phase-free method with virtual convergence light to address this problem.
