相位分辨光学相干层析成像(OCT)的噪声统计是复杂的，涉及到OCT噪声、信号相关性和散斑。本文给出了含有加性随机噪声和散斑噪声的两个OCT信号之间相移的统计特性。用散射组织体模得到的实验结果与理论预测符合得很好。比较了双波束方法和常规单波束方法的性能。不出所料，当横向采样步长较大时，双波束扫描法的相移噪声要小于单波束扫描法。
Noise statistics of phase-resolved optical coherence tomography (OCT) imaging are complicated and involve noises of OCT, correlation of signals, and speckles. In this paper, the statistical properties of phase shift between two OCT signals that contain additive random noises and speckle noises are presented. Experimental results obtained with a scattering tissue phantom are in good agreement with theoretical predictions. The performances of the dual-beam method and conventional single-beam method are compared. As expected, phase shift noise in the case of the dual-beam-scan method is less than that for the single-beam method when the transversal sampling step is large.
