摘要:
光反馈自混合干涉效应在光电信号处理中具有广泛应用。其中,双腔光反馈系统常用于移动物体的高灵敏度感测,其动态行为可通过Lang-Kobayashi (L-K)方程求解,而求解精度会对测量准确性产生决定性影响。因此,本文提出了一种光电信号双腔OFI系统L-K方程的六阶龙格-库塔算法,并将其应用于移动物体运动检测仿真软件中。实验结果表明:该算法提高LK方程求解精度,从而给出更精确的仿真结果;与欧拉法相比,求解精度平均提高了约22%;与四阶龙格库塔算法相比,求解精度平均提高了约6%。本文为开发激光传感提供了有力的工具。
Abstract:
The optical feedback self-mixing interference effect is widely used in photoelectric signal processing. Among them, the dual-cavity optical feedback system is often used for high-sensitivity sensing of moving ob<x>jects. Its dynamic behavior can be solved by the Lang-Kobayashi (L-K) equation, and the accuracy of the solution will have a decisive influence on the measurement accuracy. Therefore, this paper proposes a sixth-order Runge-Kutta algorithm for the L-K equation of the photoelectric signal dual-cavity OFI system, and applies it to the simulation software for moving ob<x>ject motion detection. Experimental results show that the algorithm improves the accuracy of solving the LK equation, thereby giving more accurate simulation results Compared with Eulers method, the solution accuracy is improved by about 22% on average Compared with the fourth-order Runge-Kutta algorithm, the solution accuracy is average An increase of about 6%. This paper provides a powerful tool for the development of laser sensors
