论文摘要
在计算机生成的全息投影系统中，图像是通过从空间光调节器中的光衍射重建的。在此过程中，几个因素可能导致重建和目标图像之间的非线性。本文使用使用一步相检索（OSPR）算法计算的二进制相全息图评估了整体全息投影系统的非线性，然后应用数字前（DPD）方法来校正非线性。重建质量的显着提高和平均平方误差的显着降低，证明了拟议的DPD-OSPR算法的有效性。
In a computer-generated holographic projection system, the image is reconstructed via the diffraction of light from a spatial light modulator. In this process, several factors could contribute to non-linearities between the reconstruction and the target image. This paper evaluates the non-linearity of the overall holographic projection system experimentally, using binary phase holograms computed using the one-step phase retrieval (OSPR) algorithm, and then applies a digital pre-distortion (DPD) method to correct for the non-linearity. Both a notable increase in reconstruction quality and a significant reduction in mean squared error were observed, proving the effectiveness of the proposed DPD-OSPR algorithm.
