提出了一种配备二维激光阵列的非机械紧凑光学终端。通过选择与从计数器终端接收到的光信号的方向相对应的激光像素来发射激光束。光束不会被机械镜偏转。相反，它们根据接收光信号的方向依次打开和关闭。在此配置中可以进行多输入多输出操作。非机械收发器可以有利于减小光学系统的尺寸。本文提出了用于光无线通信的带有二维激光阵列的非机械紧凑型收发器的基本概念。
A non-mechanical, compact optical terminal equipped with a two-dimensional laser array is proposed. A laser beam is transmitted by selecting the laser pixel corresponding to the direction of the optical signal received from the counter terminal. The beams are not deflected by a mechanical mirror. Instead, they are turned on and off one after the other in accordance with the direction from which optical signals are received. Multiple-input multiple-output operation is possible in this configuration. The non-mechanical transceiver can facilitate a reduction in the size of the optical system. This paper presents the basic concept of a non-mechanical compact transceiver with a two-dimensional laser array for optical wireless communications.
