摘要 提出了适用于光聚物厚膜盘状高密度全息存储的角度空间复用相结合的存储方法。研究了光路设置对记录容量和密度的影响 ,分析和计算表明 :对全息光盘光聚物全息存储介质来说 ,新方法可以获得比空间角度复用存储方法高近一个数量级的存储容量和密度 ,当使用平面波做参考光、介质内参物光入射角度在 32°时是获得最大存储容量和密度的最佳设置 ;对 5 0 0 μm厚的光聚物介质 ,存储密度可达到 42bit/ μm2 ,用CD ROM同样大小的全息光盘 ,在其相同的有效记录面积上 ,其总容量可以达到 40 0Gbit,表明新方法是实用化光聚物盘状全息存储比较理想的方法。 A new method for disk-type photopolymer high-density holographic storage based on angular-multiplexing and spatial-multiplexing is described. The effects of optical setup on the recording capacity and density are studied. The recording optical setup for getting the maximum recording capacity and density is optimized.
