将两个光学准直器用于离轴旋转光通信系统,并分别置于通信系统中两端的旋转部件,使准直器的光轴与旋转部件的轴线平行,从而保证光信息在较大间距且相对旋转的两个筒状部件之间的可靠传输。结合光端机、光分路器、语音视频采集卡和电脑等设备,使系统具有实时传输语音视频信号的功能。实验结果表明,在旋转部件间距小于500mm,其转速小于120r/min的条件下,系统满足1.25Gbit/s的高速率光信号的稳定传输。
Two optical collimators are used for off-axis rotating optical communication system and are respectively placed on the rotating components at both ends of the communication system so that the optical axis of the collimator is parallel to the axis of the rotating component so as to ensure that the optical information is at a large distance Reliable transmission between two rotating cylindrical parts. Combined with optical equipment, optical splitters, voice and video capture cards and computers and other equipment, the system has real-time transmission of voice and video signals. The experimental results show that the system can meet the stable transmission of high speed optical signal of 1.25Gbit / s under the condition that the rotating components are less than 500mm and the speed is less than 120r / min.
