摘要
在1∶1体全息存储系统的读出过程中,保证图像的不失真和降低误码率是最关键的问题。提出了一种新颖的放大率补偿算法,定量分析了放大率偏移误差对图像的影响,并通过理论推导和实验模拟证明了这一算法的可行性。
In the process to output data in pixel-matched volume holographic systems, the critical factor, is to ensure that the high fidelity and low Bit-Error-Rate of the retrieved page. A novel method named magnification compensation algorism was proposed, which was a post-procesing to compensate for pixel shifts produced by magnification error, Furthermore, this method is demonstrated by quantitative analysis and numerical experiments, whose results show a high feasibility and significant improvement in the read out system,
