Investigation of atmospheric polarization information measurement method imitating POL-neurons of cataglyphis

大气偏振模式是太阳光在大气传输过程中,由于大气的散射作用而产生的偏振光所形成的特定的偏振态分布。大气偏振模式中蕴涵着重要的导航信息,大气偏振模式信息的有效获取是实现利用自然偏振光导航与定位的前提,本文根据沙蚁复眼中特殊的偏振敏感神经元结构,提出了一种仿沙蚁POL-神经元的偏振信息检测方法,并设计了检测系统。检测实验结果表明,该方法实现了POL-神经元对大气偏振模式信息的快速处理功能,实现了大气偏振模式中罗盘信息的准确检测。

Atmospheric polarization pattern is the specific polarization state distribution formed by the polarization light, which is caused by the sunlight scattering during the process of atmospheric transmission. Significant information about navigation is included in the atmospheric polarization pattern. Effectual information acquisition of the atmospheric polarization pattern is the precondition to realize navigation and localization using of the natural polarized light. A method of polarization pattern information acquisition was proposed by imitating POL-neurons and a measurement system was designed, which is based on the special nerve structure of the Cataglyphis＇s compound eye that is sensitive to polarization. The measurement results indicate that the method can implement quick processing function of the POL-neurons to the atmospheric polarization pattern information. The information measurement of atmospheric polarization pattern is achieved accurately.
