摘要

概要分析了沙蚁等昆虫视觉系统的偏振敏感机理,设计了一种模仿昆虫视觉系统中偏振敏感(POL)神经元的偏振光导航传感器,阐述了传感器的工作原理和主要功能结构,并给出了传感器的实际检测实验结果.实验结果表明,该传感器实现了类POL神经元对大气偏振信息的快速感知,能够实时获取偏振化方向,且具有较高的精度,能够满足偏振光导航的实际需求.%Polarization sensitive mechanism of the vision system of insects such as desert ant is analyzed briefly, and a polarized light navigation sensor imitating POL neurons in insects' vision system is designed. Working principle and main functioning structure of the sensor are introduced. The experimental results are given. It demonstrates that the sensor can implement quick perception of atmospheric polarization information similar to POL neurons, and it can realize real-time acquisition of polarized light direction. Its high precision meets the practical need of polarized light navigation.
