摘要 分析了使用差分探测器的偏振光学相干层析(PS-OCT)系统噪声,讨论影响系统信噪比(SNR)的因素,模拟SNR随这些因素的变化趋势,根据分析得出实现最佳SNR的参数条件,为提高PS-OCT系统SNR提供了理论依据。相关实验验证了模拟结果的正确性。 We analyzed the noise in polarization-sensitive optical coherence tomography(PS-OCT) with single balanced detector and discussed the system signal to noise ratio(SNR).Besides,we simulated the relationship of SNR vs.its influence factors,and got the optimized parameters of system,which is helpful for increasing SNR of PS-OCT.The experiment validated our simulation results.
