大气光学偏振模式中包含了丰富的方向和位置信息,通过有效提取和利用大气偏振模式信息,可以实现一种全新概念的自主导航定位方式。E-矢量是其偏振信息中最为关键和最为稳定的参数,仿照昆虫的导航偏振敏感机理,设计了一种仿生复眼光学偏振传感器;根据昆虫的POL-神经元的信号处理方式,推导出传感器输出信号数学处理方法;对传感器进行了测试实验并在不同天气下对大气偏振模式中E-矢量方向进行检测。通过对晴朗无云的天气大气偏振模式进行检测,偏振E-矢量平均误差为0.467 52°。对大气E-矢量的检测表明仿生复眼光学偏振传感器能够实现对大气偏振模式的准确检测,为偏振光导航这一自主导航系统发展奠定了基础。
Atmospheric optical polarization mode contains a wealth of direction and location information, through the effective extraction and utilization of atmospheric polarization mode information, you can achieve a new concept of autonomous navigation positioning. E-vector is the most critical and stable parameter in its polarization information. A biomimetic compound-eye optical polarization sensor is designed according to the insensitive navigation polarization sensing mechanism. According to the POL-neuron signal processing method of insects, the sensor output Signal processing method. The sensor was tested and the E-vector direction of atmospheric polarization mode was detected in different weather. By detecting the cloudless weather pattern of atmospheric polarization, the average error of polarization E-vector is 0.467 52 °. The detection of the E-vector of the atmosphere shows that the biomimetic compound-eye optical polarization sensor can accurately detect the atmospheric polarization mode, which lays the foundation for the development of the autonomous navigation system with polarized light navigation.
