line defect

Photonic crystal waveguide ( PCW) which is composed by introducing a line defect is one of the important components for constructing the future photonic integration circuits.

光子晶体波导是构建未来光子集成回路的重要部件之一，其是通过在完整光子晶体中引入线缺陷而形成。

Rebuild the point image by synthetic aperture focusing imaging algorithm and add these images together each with a displacement of one probe element. Use the result acquired to take the place of line defect image rebuilt by synthetic aperture focusing algorithm.

对每个点缺陷的图像采用合成孔径聚焦算法重建后依次按一个阵元错位相加，以所得结果来表示线缺陷的合成孔径聚焦成像结果。

The algorithm with fast speed has been successfully utilized line defect detecting system for printed matter.

算法处理速度较快,已经成功运用到印品缺陷在线检测系统中.
