We propose and demonstrate a modified-signed-digit (MSP) arithmetic to achieve multi-input digital optical computing. Our approach utilizes hybrid addition-subtraction transformation (or weight operation) rules among multiple inputs. This results in operation speeds that exceed those of two-input MSD arithmetic for multi-input computing. Optical'implementation of the proposed multi-input MSD arithmetic by utilizing spatial data encoding and an optical fan-out element is also presented and experimentally demonstrated.
我们提出并演示了一种改进的符号数（MSP）算法，以实现多输入数字光学计算。我们的方法利用了多个输入之间的混合加减法变换（或权重运算）规则。这使得在多输入计算中，运算速度超过了双输入MSD算法。还介绍并通过实验演示了利用空间数据编码和光学扇出元件对所提出的多输入MSD算法进行光学实现。
