我们提出了一种算法的光互连的二维阵列通过传输输入通过相位码掩模，然后将其与控制图像构造的互连权重。可以对任意复数加权互连图案进行编码。我们展示了如何通过调整相位码特征尺寸来控制图像尺寸和复杂度，从而实现输出信噪比的交易。平均输出信噪比的理论计算与计算机模拟的算法进行了比较。
We present an algorithm for optical interconnection of two-dimensional arrays by transmitting the input through a phase-code mask then correlating it with a control image constructed from the interconnection weights. An arbitrary complex-weighted interconnection pattern can be encoded. We show how the output signal-to-noise ratio can be traded for control image size and complexity by adjusting the phase-code feature size. Theoretical calculations of the average output signal-to-noise ratio are compared with computer simulations of the algorithm.
