| 摘 要： | 对方形波导的图像传输问题进行了理论分析与探讨,推导出其自成像周期,并借助于数值方法模拟其图像传输特性.结果表明:二分之一自成像周期截面具有成反像的特性;四分之一自成像周期截面可成四个自成像,其他位置的图像与输入位置的图像依次关于y轴、原点和x轴对称.

| Abstract: | In this paper,image transmission through a square optical waveguide is discussed in theory.Self-image length of this waveguide is derived;and image transmission on the waveguide is studied by numerical simulation.The result shows:the output image at half of the Self-image length shifts from the first quadrant to the third quadrant;And four identical images at one forth of the Selfimage length distribute symmetrically. |

| Keywords: | Square optical waveguide Image transmission Self-image |
