Abstract: In order to improve the measurement accuracy and long-term stability of OCT in low SNR(signal-noise ratio) environment,this paper starts from the algorithm that one of the key factors affects the performance of OCT.Basing on the analysis on existing variable step size adaptive algorithm,combining the characteristics of the output signal of OCT and the working circumstance of OCT,we proposed an improved double Sigmoid function variable step size adaptive algorithm,and compared this algorithm with the existing variable step size adaptive algorithm through simulation.Then,the algorithm is tested in OCT based on ActiveX.The results demonstrated the advantage of this algorithm in improving the measurement accuracy and long-term stability of OCT in low SNR environment.
