In swept source polarization depth encoding polarization sensitive optical coherence tomography (PS-OCT), the laser jitter induces additional noise to the polarization sensitive measurement. In this Letter, we developed a numerical algorithm to correct the jitter phases based on the image data using the Mueller matrix calculus. The algorithm was demonstrated on in vivo retina imaging of a guinea pig with a custom-built PS-OCT system. The performance of the proposed algorithm was almost comparable to the conventional method of using a physical calibration signal. By not requiring a hardware generated calibration signal and -clock, the proposed algorithm is useful to reduce the complexity and the cost of a polarization depth encoding PS-OCT system.
在扫频源偏振深度编码偏振敏感光相干断层扫描（PS-OCT）中，激光抖动会给偏振敏感测量带来额外的噪声。在这封信件中，我们使用 Mueller 矩阵微积分，基于图像数据开发了一种数值算法来校正抖动相位。该算法在使用定制 PS-OCT 系统对豚鼠进行体内视网膜成像中得到了验证。所提出的算法的性能几乎与使用物理校准信号的传统方法相当。由于不需要硬件生成的校准信号和时钟，因此该算法有助于降低偏振深度编码 PS-OCT 系统的复杂性和成本。
