摘　　要：偏振信息的有效获取是实现偏振光导航的重要前提。仿照沙蚁复眼的偏振敏感视觉神经结构设计了一款三通道式仿生偏振光传感器,该传感器以ARM微处理器为处理核心,每个天空偏振光感知通道包含两个覆盖极化方向垂直偏振片的光电二极管与对数放大器,设计的偏振光传感器具有结构紧凑、实时性好且成本较低的优点,并设计了传感器稳定性与采集精度检测方案。试验结果表明,该传感器检测到的偏振角误差在±3.9°之内,平均误差为1.53°。该仿生偏振光传感器能实现偏振信息的有效检测、实时采集与存储,且具备稳定的采集能力,并在最后分析了传感器的误差产生原因及下一步的改进措施。Effective acquisition of polarization information is an important prerequisite for polarization navigation.A threechannel polarization navigation sensor which based on the polarization sensitive structure of sand cataglyphis ommateum is designed.The sensor takes ARM microprocessor as the processing core,and each sky polarization sensing channel consists of two photodiodes which are covered polarizers with mutually perpendicular polarization directions,and logarithmic amplifiers.The polarization sensor has the advantages of compact structure,good realtime performance and low cost.The detection scheme of sensor stability and acquisition accuracy is designed.Experimental results show that the detection error of the polarization angle detected by the sensor is within ±3.9°,and the average error is 1.53°.This sensor can effectively detect,collect and store polarization information in real time,and it has stable acquisition ability.Finally,the causes of polarization sensor error and the improvement measures are analyzed.
