中文摘要：

在许多光电系统中，如激光雷达、激光通信、光电探测等，对其滤光和鉴频的能力提出了越来越高的要求。采用传统的光学高分辨技术满足这些应用要求，存在高光谱分辨率与系统稳定性、技术复杂性、甚至成本的矛盾，而采用基于原子跃迁的高分辨光学技术（即原子滤光技术），可以在很大程度上缓解这一矛盾。在光电系统接收端采用原子滤光技术后，在其发射端也必须采用同种原子的同种跃迁控制激光波长，从而构成了原子控制的光学信道。介绍了原子控制光学信道的作用、原理、构成，以及几种采用原子控制信道进行高分辨率滤光和高精度鉴频的光电系统。．

英文摘要：

In many opto-electronic system, the requirements to the ability of optical filtering and optical frequency discrimination become higher and higher. If the traditional optical techniques are used, the problems of system stability, technical complications and costs of the system will be encountered. However, by using the high optical resolution technique based on atomic transitions, most of problems mentioned above can be overcome. When the atomic transition technique is used in the optical receiver, the same technique must be used in optical transmitter to control the laser frequency. In this way, an atomic transition controlled optical channel is formed. Here the function, principle and structure of an atomic controlled channel and some opto-electronic system using atomic channel technology are presented.
