In terms of the refraction angle measured at the metal/air interface, we quantitatively obtained the relationship between the value of pseudo refractive index and incidence angle.

改进的途径是设法寻找到负折射率材料，与正折射率材料匹配在一起，预期可形成完美光学透镜。

The mechanism is composed of two ball screws, U-type linear rails, linear bearings and flexible couplings. The permanent magnetic direct current motors are used as actuators. The rotary encoder is used to measure the angular position of the DC motor. The digital controller is implemented on the personal computer and a motion control card (EPCIO-6000). The objective of this thesis is to realize precise positioning control using a real-time motion control system on an X-Y table.

机械结构包括有滚珠导螺杆、U型线性滑轨组、线性轴承及可挠性连轴器等；致动器是采用永磁式直流马达(permanent magnetic direct current motor)；感测器是使用光学式旋转型编码器来量测马达旋转的角度；控制器则是以个人电脑为控制核心，搭配运动控制轴卡(EPCIO-6000)所组成。
