The double phase method is an efficient way to generate phase-only holograms. However, it cannot directly encode the Fourier spectrum because of the limited gray modulation range of spatial light modulator and quantization error. The proposed method overcomes this shortage and can reconstruct high-quality images compared to the non-iterative bidirectional error diffusion method (Non-BERD). Moreover, it outperforms the Non-BERD in calculation speed with approximately 34 times faster.

基于双相位法的纯相位傅立叶全息图生成及量化误差分析


双相方法是生成纯相位全息图的有效方法。然而，由于空间光调制器的灰度调制范围有限以及量化误差，它不能直接对傅里叶频谱进行编码。所提出的方法克服了这一缺点，与非迭代双向误差扩散方法（Non-BERD）相比，可以重建高质量的图像。此外，它的计算速度比 Non-BERD 快约 34 倍。
