AI Technical Summary
Technical Problem
Existing OCT imaging methods are only compatible with unidirectional frequency sweep mode and cannot be used with bidirectional frequency sweep mode, resulting in low imaging efficiency.
Method used
By acquiring forward and reverse frequency sweep data within the sweep cycle, phase correction processing is performed, including phase shifting, resampling, and dispersion compensation, to ensure that the forward and reverse frequency sweep data are phase matched in the frequency domain, thereby determining the OCT image.
Benefits of technology
This invention enables OCT imaging in bidirectional frequency sweep mode, improving imaging efficiency and solving the problem that traditional methods are incompatible with bidirectional frequency sweep.

Abstract
本申请提供了一种OCT成像方法，涉及数据处理技术领域。方法包括：获取一个扫频周期内的第一扫频阶段对应的第一扫频数据和第二扫频阶段对应的第二扫频数据，第一扫频阶段和第二扫频阶段的扫频方向相反；对第一扫频数据进行相位校正处理，以获得相位校正处理后的第一扫频数据，并根据第二扫频数据和相位校正处理后的第一扫频数据确定第三扫频数据和第四扫频数据；基于第三扫频数据和第四扫频数据确定OCT图像。采用本方法能够适配双向扫频模式。
