optical channel

Based on the needs of this type of system, optical channel is proposed, the relation of the focus and view field is concluded according to the principles of imaging and the function of adjusting focus is realized.

结合该类系统的需要，提出了光学通道的概念。根据摄像机成像原理，得到了焦距与视场角的关系，实现了光学通道的变焦功能。

In these key technologies, this paper laired emphasis upon influence resulted from optical channel.

在关键技术中, 重点分析了大气信道对空间激光通信造成的影响.

RPR is a new data-oriented technique that can be used to transmit data information in optical channel. It can not only keep the reliability of SONET/ SDH, but also can allocate the bandwidth more fairly and transmit data more effectively.

RPR是一种可利用光传输通道的面向数据通信的新技术，它不但保留了SONET/SDH的可靠性，而且比传统的SONET/SDH能更有效地分配带宽和传输数据。

Winsock is adopted to accomplish the data communication between optical channel and image tracking system.

上述图像跟踪模块与光学通道之间的数据交换采用基于WinSock的网络通信来实现.
