摘要
与其他复眼相比,虾蛄眼可以识别圆偏振光,这种特性对于偏振探测和目标识别的研究有很大的帮助,并为进一步仿生虾蛄眼偏振模型奠定了基础。首先利用斯托克斯算法与偏振光强吸收相结合,对虾蛄眼识别圆偏振光机理进行解析;其次,通过对虾蛄眼的生物特征参数进行了测试,获得微绒毛尺寸;最后,根据所测得的特征参数,在VirtualLab中模拟虾蛄眼识别圆偏振光的光路,得到模拟结果 R145所吸收的能量为957.87 W,R2367所吸收的能量为0 W,S3为1,χ为90°,判断出圆偏振光的旋向,从而验证虾蛄眼识别圆偏振光机理的解析。
The most prominent difference between Mantis shrimp eyes and other compound eyes is that it can identify the cir- cularly polarized light. It is helpful to the study on object detection and identification,and can provide important support for polarized light identification bionic optical system. Firstly, with the combination of Stokes algorithms and intensity absorp- tion, the circularly polarized light identification mechanism is calculated in detail. Secondly, with the experiment of mantis shrimp eyes biometric parameters tested, the microvilli size is obtained. Finally, according to the characteristic parameters measured, the light path of mantis shrimp eye recognition circularly polarized is simulated in the VirtualLab. The results of simulation show that energy absorbed by R145 is 957. 87 W, the energy absorbed by R2367 is 0 W, S3 =1, X=90°. And then the direction of the circularly polarized light is judged, thus the circularly polarized light identification mechanisms of mantis shrimp eyes is verified.
