查询词典 optical scanner

The rotary connection can be carried out in free space and hi-direction transmission of optical signal can be performed. Through analyzing the design principle of the optical structure and optical path calculation, it is found that when the ratio between the focal lengths for two lens is 20~50 and off-axis distance is in the range of 4~10mm, the interference will not be occurred between two optical channels and signal transmission can be lasted.

在自由空间可以实现旋转连接并实现光信号的双向传输，通过分析该光学结构设计原理和光路计算，发现每组透镜中两个透镜焦距之比为20-50，离轴距离为4-10mm范围时，才能保证光通道之间不发生干扰且信号持续传输。

The main content includes as the follows:(1) An automatic neighbor discovery mechanism applicable to SDH network is proposed;(2) For the optical network with Optical Transfer Unit in WDM, a General Multi-protocol Label Switch-based automatic neighbor discovery mechanism is proposed and simulated;(3) Three automatic neighbor discovery mechanisms for the all-optical network with OEO module are proposed and comparatively simulated;(4) With the Loss of Light detecting, a novel automatic neighbor discovery mechanism in all-optical network without any OEO module is proposed.

主要工作包括：（1）提出了SDH网络的自动邻居发现机制；（2）提出了带波长转换器的光网络的自动邻居发现方案，并通过仿真对发现过程进行了跟踪和统计；（3）提出了三种带有光电转发模块的光网络的自动邻居发现策略，并做了仿真比较；（4）提出通过光丢失检测方式对不带OTU的光网络进行自动邻居发现的实现方法。

Optical fiber communication is transferring form point-to-point transmission to mesh network. Traditional optical-electronical-optical transformation limits the data rate and adds the cost. With reconfigurable optical add/drop multiplexer for signal switching and routing, the OEO transformation can be bypassed, reduceing equipment size and cost.

光纤通信由点到点传输向网格化发展，传统的光—电—光转换过程限制了通信速率并导致成本增加，采用可重构光分叉复用器进行光交换和光路由，可以省去光—电—光转换过程，缩小尺寸和降低成本。
