Due to the numerical aperture of DVD pickup is large, and the characteristic size is small, the error of scalar diffraction theory is very large. The in-depth research work on vector diffraction of optical disc was carried out. The optical disk model was analyzed use the rigorous coupled wave theory, and some significative conclusion was obtained. These conclusions can use for guidance of scheme designing of optical pickup.

针对DVD读取头光学系统数值孔径大，光盘特征尺寸小，标量衍射理论误差大等缺点，采用矢量衍射理论对光盘的衍射进行了深入的研究，首次在光学读取头领域中将耦合波理论应用到光盘的衍射分析中，得到了一些有意义的结果，这些结果可以用来指导光学读取头方案的设计。
