抽象的。复眼透镜有望应用于高速目标跟踪和深度感知。然而，由于CEL的形状和结构复杂，因此难以制备。我们研究了它的数学模型和光学模型。基于所建立的模型，提出了一种网格加工方法，用于CEL模具的制造。为了避免刀具不对中引起的形状变形，提出了偏心加工方案，并通过实验验证了偏心加工方案的有效性。最后，使用已加工好的模具通过成型工艺加工CEL，以避免刀具干涉。实验验证了设计和制作方法。最后通过形状精度评定和光学测试验证了该方法在电火花线切割加工中的有效性。
Abstract. Compound eye lens (CEL) is expected to be applied in high-speed object tracking and depth perception. However, it is difficult to fabricate CEL due to the complex shape and structure. We study its mathematic and optical model. Based on the established model, a grid machining method is proposed for the fabrication of a CEL mold. To avoid the shape distortion caused by tool un-alignment, the off-centering machining configuration is proposed, which is also proved to improve the form accuracy. CEL is machined finally by molding technologies using the fabricated mold to avoid the tool interference. Experiments have been implemented to verify the design and fabrication method. The shape accuracy evaluation and optical testing are conducted to prove that the proposed method can be applied well for the machining of CEL.
