电/光接口的响应时间一直限制着传给光纤线路的数据量。因此,人们正在致力于研究并试验构建信号处理和通讯系统所用的全光学系统。在雷达中,很多注意力被集中到包括调制器、开关和多路器的这些光学元件应用于相控阵系统中有源单元的寻址和控制的可能性上。在这种情况下,这些元件被组合起来,以产生射频信号,将信号按调整波束形状所需的方式引到有源单元中,并精确地控制信号在阵列上的相对相位。
The response time of the electrical / optical interface always limits the amount of data that is transmitted to the fiber optic line. As a result, people are working on researching and experimenting with all-optical systems used to build signal processing and communication systems. In radar, much attention has been focused on the possibility of applying these optical elements, including modulators, switches and multiplexers, to the addressing and control of active cells in phased array systems. In this case, these elements are combined to produce a radio-frequency signal, which is directed into the active cell in the manner required to adjust the beam shape and to precisely control the relative phase of the signal on the array.
