分析了ＯＣＴ系统中严重影响象质的“双峰值效应”，指出其起源为参考反射镜的介质高反膜，并通过建立相应的数学模型研究了其恢复的算法。从理论上推导了考虑双峰值效应后的ＯＣＴ系统点扩展函数。用平均平滑周期图法分别估算出信号与噪声的功率谱密度函数。最后用维纳逆滤波算法得到恢复图象，避免了普通逆滤波中的病态问题。该算法也可同时恢复因光谱有限带宽、象差等引起的图象降质。
The “double-peak effect” of OCT system which seriously affects the image quality is analyzed, and the origin of the high-reflection film of the reference mirror is pointed out. The corresponding mathematical model is used to study its recovery algorithm. The point spread function of the OCT system considering the double peak effect is deduced theoretically. The power spectral density function of the signal and noise is estimated using the average smoothing period diagram method. Finally, the Wiener inverse filter algorithm is used to obtain the recovered image, which avoids the ill-posed problem in the common inverse filter. The algorithm can also restore the image degradation caused by the limited bandwidth and aberration of the spectrum at the same time.
