摘要
介绍了并行谱域光学相干层析成像（PSD-OCT）技术，重点报道了丁志华课题组在PSD-OCT的方法与系统研制方面取得的研究进展，包括基于全局优化的大视场PSD-OCT系统、基于复干涉信号与相位信息的真伪缺陷识别方法及基于空间光谱编码与重叠数据互相关算法的运动伪影校正方法。利用所建立的PSD-OCT系统，可实现玻璃表面及内部缺陷的检测，避免伪缺陷的误判。通过引入空间光谱编码单元，该系统还可校正非受控运动。
Abstract
Parallel spectral domain optical coherence tomography (PSD-OCT) technology is introduced. Research progresses on the method and system development of PSD-OCT in Zhihua Ding′s group are mainly reported, which includes the wild-field PSD-OCT system based on global optimization, the discrimination method for real and fake defects based on the complex interference signal and phase information, and the approach for correcting motion artifacts based on the spatial-spectral encoding and overlapped data correlation algorithm. The established PSD-OCT system can be used to identify the surface and internal defects of glass, which avoids the misjudgment of fake defects. With the introduction of spatial-spectral encoding units, this system can also be used to correct uncontrolled motions.
