摘要 在重叠复眼的生物结构中,晶锥部分的折射率随半径的增大逐渐变小,与渐变折射率(GRIN)介质十分相似。复眼具有体积小、重量轻、视场大、灵敏度高等优点。近年来,在智能武器、智能机器人视觉系统和微型飞行器等领域中,复眼光学系统得到了越来越多的应用。GRIN介质在重叠复眼光学系统中对会聚光线起到了关键的作用。从理论上对其进行了分析,得到了GRIN介质适用于重叠复眼光学系统中的条件;深入分析了GRIN介质出射光线聚焦点的位置关系;讨论了与重叠复眼灵敏度的关系。 In the superposition compound eye structure,the refraction index of the crystal cone gets smaller when the radius gets bigger,that is similar to the GRIN.Compound eye has the advantages of small volume、light weight、 large FOV and high sensitivity.Recently,it has been used in the artificial intelligence weapons、vision system of the artificial intelligence robot and micro-aerocrafts.GRIN plays an important role in the superposition compound eye optical system to focus the rays.The theory is analyzed,the condi...
