光传操纵系统的关键性技术初步研究

光传操纵系统的性能和可靠性取决于光源、光纤和光检测器等光电器件,光电器件的选择是成功设计光传操纵系统的关键之一。针对国内光传操纵技术的发展现状,在自行开发光传操纵系统的前提下,对光源、光纤、光检测器等关键性器件的选择与集成开发进行了试验性的研究。同时经过高温实验以及高空环境模拟实验,验证了某种特制多模石英光纤能满足光传操纵系统的要求。并利用所选器件设计了一种光传操纵系统的实现方案,初步结果表明了该方案的可行性。

Study on Key Techniques of Fly-by-light System

The performance and reliability of the fly-by-light(FBL) system lies on the photoelectric unit such as the lamp-house,the optical fiber,photodiode,and so on.The proper choice of the photoelectric unit is one of the key points to design a FBL system successfully.Aimming at the development actuality of FBL in our country,and at the precondition of the the photoelectric unit developing independent,a study is carried out about the choice and development of the photoelectric unit.After the detailed tests at a high temperature and simulating the flght surrounings,a kind of multimode quartz fiber is validated that it can meet the request of the FBL.At last,an implement scheme is designed in the use of the chosen device.The elementary result indicates that the design is feasible.
