space laser communication的意思|示意

Laser beam's acquisition, tracking and pointing is one of the key technologies of free space optical communication.

首先需要解决实现空间光通信的关键问题是光束的捕获、跟踪和瞄准。

Acquisition, pointing and tracking (APT) is the key technology in free space laser communication with the characteristics of high precision and large bandwidth.

高精度、宽带宽的激光捕获、对准和跟踪(APT)技术是自由空间激光通信的关键技术。

By Comparison with microwave communication, the advantages of the free-space laser communication system, such as big capacity, low power consumption, small volume and light weight, are introduced.

通信领域中激光通信技术由于自身的优越性得到了广泛的应用。通过将空间激光通信与微波通信比较，介绍空间激光通信的优点：大容量、低功耗及体积小、质量轻等。

But in the harsh conditions, such as the becoming temperature in free space experiments, these two methods can not guarantee linear laser modulation, effects of poor communication.

但在温度等条件恶劣的自由空间实验中，这两种方法都不能保证激光线性调制，通信效果很差。

The most typical weather restriction of Free-space Optical Communications System is the fog; the fog attenuation of laser is a main factor that affects the performance of the lasers communication.

雾是制约无线光通信系统的最典型气象条件，它对激光的衰减效应是影响光通信性能的主要因素。

At present, because of national space laser communications experiment progresses, it is very urgent to solve some of the key laser communication technologies.

目前由于各国光通信试验的不断推进，解决光通信中的一些关键技术就变得刻不容缓。
