仿生偏振导航光电测试系统的设计与实现

摘要

In order to verify the directional mechanism of bionic polarization navigation and meet the need of further building up the high precision model of polarization navigation, a photoelectricity test system is designed for detecting angle information of the polarized light in the sky, which can measure the angle between the current system direction and the solar meridian. The mechanism of how insects use the polarized light to navigate is analysed. According to the mechanism, the hardware system is designed. The response model of the polarized-light sensor is derived. The experimental data is processed by the simultaneous model of polarization navigation. The experimental result show that the bionic polarization navigation is feasible and the design of the photo-electricity test system is effective. This has laid a foundation for the further research on polarization navigation.%为了验证仿生偏振导航定向机理和进一步建立高精度偏振导航模型的需要,设计了探测天空偏振光方向信息的光电测试系统,能够测出载体当前方向和太阳子午线之间的夹角.分析了昆虫利用偏振光导航的机理,按照机理设计了相应的硬件系统；推导了偏振光传感器的响应模型,用偏振导航并发式模型对获取的数据进行了处理.实验结果表明了仿生偏振导航的可行性和光电测试系统设计的有效性,为偏振导航的深入研究奠定了基础.
