从理论和实验两方面研究了反射全息滤光片的性能 .结果表明 ,反射全息滤光片不仅具有高光密度 (大于 4D)和窄带宽 ,还具有很好的调谐性能 .同时 ,对均匀介质和非均匀介质两种耦合波理论模型进行了比较分析 ,证明非均匀介质耦合波理论模型更加符合实验结果
The performance of the reflection holographic filter is studied theoretically and experimentally.The results show that the reflection holographic filter not only has high optical density (greater than 4D) and narrow bandwidth, but also has good tuning performance.At the same time, Inhomogeneous medium two kinds of coupling wave theory model were compared and analyzed to prove that the heterogeneous medium coupled wave theory model more in line with the experimental results
