摘　　要：针对传统的滑环存在通信宽带不足、接触磨损寿命低的问题,设计了一种基于空间激光通信的离轴盘式无线光滑环,并完成了样机研制。该光滑环采用光学追迹仿真技术,将4个红外发射器均匀等间距地布置在光滑环的4个角,使接收端旋转时能连续稳定地接收到光功率。光学仿真和性能测试结果表明:在传输距离为20~200 mm时,离轴盘式无线光滑环的接收功率为-28.3~-29.2 dBm,满足探测器灵敏度(约-30 dBm)的要求;在0~500 r/min旋转环境下,其误码率会随着传输距离的增加而增大,但整体误码率均小于10-6。Aiming at the problems of insufficient communication broadband and low contact wear life of traditional slip ring,an off-axis disc type wireless smooth ring based on space laser communication is designed and a prototype is developed.The smooth ring uses optical tracking simulation technology to arrange four infrared emitters uniformly and equally at four corners of the smooth ring,so that the optical power can be received continuously and stably when the receiving end is rotating.The optical simulation and performance test results show that the receiving power of the off-axis disc type wireless smooth ring is-28.3~-29.2 dBm when the transmission distance is 20~200 mm,which meets the requirement of detector sensitivity(about-30 dBm).In the 0~500 r/min rotation environment,the bit error rate will increase with the increase of transmission distance,but the overall bit error rate is less than 10-6.
