摘要

提出了基于互相关的多普勒OCT(correlated Doppler optical coherence tomography, CD-OCT)方法, 能够有效的抑制噪声, 实现低信噪比条件下的流速探测. 对CD-OCT算法进行了详细的推导, 分析了噪声的相关性对该算法结果的影响, 最后基于谱域和时域联合探测方法(joint spectral and time domain optical coherence tomography, STD-OCT)以及CD-OCT算法的对比实验证明了该算法能够进一步实现信噪比的提高, 使测量的结果更为稳定.

Abstract

A new method based cross-correlation technique (CD-OCT) is proposed to acquire and analyse the information about flow velocity with low signal-to-noise ratio(SNR) in spectral-domain optical coherence tomography(SD-OCT). We theoretically study the procedure of this method, and analyse the correlation between the noises by computer simulation and experiment. The Doppler flow images reconstructed by CD-OCT are compared with those reconstructed by Joint spectral and time-domain optical coherence tomography (STD-OCT). The results demonstrate that CD-OCT can significantly improve the SNR, thus rendering it suitable for the flow measurement in low SNR.
