对重叠复眼进行简化模拟与分析的新方法

Novel method to simulate and analyze superposition compound eye

提出了一种对重叠复眼进行简化模拟与分析的新方法。通过对同一个小眼追迹多束相互倾斜的光线来分析不同小眼对感杆束上光强分布的影响,避免了在建模过程中大量计算各个小眼的三维坐标,大大简化整个建模过程。文中利用这种方法在ZEMAX软件中进行了实例模拟,对同一个小眼追迹6束光线,相对应探测器上得到的归一化光强分别为0.7823、0.7847、0.7733、0.4805、0.1095、0.00193,分析结果证明这种方法能够对重叠型复眼进行准确的模拟与分析。

A novel method to simulate and analyze the superposition compound eye simply and easily was put forward. The effect of the different ommatidia on the light intensity distribution received by a rhabdom could be obtained by analyzing the different rays focused by one ommatidium. In this way, calculation working for 3D coordinate of each ommatidia could be simplified, so that the modeling process became much simpler. The simulation of a superposition compound eye was completed by this method in the ZEMAX software, simulation results show that the normalized intensity distribution on the corresponding detectors are 0. 782 3,0. 784 7,0. 773 3,0. 480 5,0. 109 5 and 0. 001 93 for one ommatium and six light beams,respectively. The result proves that the simulation and analysis completed by this method is accurate.
