Abstract

In this article, simple models of optical computing circuits ($1\times 4$ demultiplexer (DEMUX), $4\times 1$ multiplexer (MUX), Boolean logic, and half-adder (HA)) are shown with mechanically controlled plane mirrors. Photographs of the proposed computational circuits are also shown. It is very useful for the school student to understand optical logic and Boolean algebra. It also shows that, computation can be possible with simple plane mirrors placed on the table. Here mirror movements are done with hand. The principle of operation of the circuits is based on reflection of light from plane mirrors. Optical devices which are used in this activity are all low-cost materials.

摘要

在本文中，光计算电路的简单模型（$1\times 4$解复用器（DEMUX），$4\times 1$多路复用器 (MUX)、布尔逻辑和半加器 (HA)) 与机械控制平面镜一起显示。还显示了所提出的计算电路的照片。了解光学逻辑和布尔代数对学生来说非常有用。它还表明，可以通过放置在桌子上的简单平面镜进行计算。这里镜子的运动是用手完成的。电路的工作原理是基于平面镜的光反射。该活动中使用的光学器件都是低成本材料。
