大孔徑光纖過渡器中光波特性分析In areas where it is still too early to promote fiber access, xdsl, ethernet or cablemodem can be deployed to provide broadband, integrated and digitized services. gradually, such ad hoc technologies should be evolving to an all fiber access network, in which fiber optics, complemented by wireless access means, will ultimately play a leading role
在發展光纖接入的條件還不成熟的地區和城市，可以選擇xdsl 、以太網技術或者cablemodem等接入技術來開展寬帶化的、綜合化的、數字化的業務，並逐步過渡到光纖接入，過渡到以寬帶光纖接入為主、無線接入為輔的寬帶接入網。Due to restriction with the array aperture transition time, traditional phased array radar works under relative narrow signal bandwidth, so this restricts the application of phased array radar in the field where high performance is demanded. however, optically controlled phased array radar ( ocpar ) adopts the photoelectron technology, counteracts the aperture transition time via the method of optical true time delay ( ottd ), so it can realize wide instantaneous bandwidth and squint - free operation ; meanwhile, it can realize the miniaturization of phased array radar and has super anti - electromagnetism interference capability
而光控相控陣雷達採用光電子技術，通過光實時延遲的方法來抵消孔徑渡越時間，可以實現相控陣雷達的寬帶寬角掃描;同時也可以使得相控陣雷達小型化，並具有強的抗電磁干擾的能力;另外，由於光纖傳輸具有損耗低、頻帶寬等固有優點，採用光纖連接雷達天線和雷達控制中心，可以使兩者的距離較採用同軸電纜有較大的提高，更有利於保護雷達控制中心。Once switches prices descend to a acceptable level in the future, this network can be easily transited to full duplex network through replacing the star coupler with fiber switch, only need upgrading driver
今後一旦交換機的價格下降到可接受的水平，直接用光纖交換機替代該網路的星形耦合器，並升級驅動程序，即可無縫的過渡到全雙工交換式網路。Second, the mode fields of a strip waveguide and some slab waveguides have been simulated by applying finite - difference time - domain ( fdtd ) method. the curvature radius ; vicinity coupling ; transition loss and power attenuation of a s - shape bend waveguide have been analysed numerically by employing wide angle finite - difference beam propagation method ( fd - bpm ), as well as the coupling loss of optical fiber and waveguide. in addition, the framework of the s - shape waveguide laser has been
其次，應用時域有限差分法，結合波導模式理論對條形與平面波導進行了模場模擬;應用廣角有限差分光束傳播法，對s形彎曲波導的曲率半徑、鄰近耦合、過渡損耗、功率衰減以及波導與光纖的各種耦合損耗進行了數值分析，並在此基礎上，對s形波導激光器的結構作了初步設計。This dissertation mainly studies information fusion estimation theory and its application to spacecraft control ; automatic diagnosis and system recovery ; strap - down attitude algorithm of fiber optic gyro and its error propagation
由於慣性系統正由框架式平臺系統逐步向捷聯系統過渡，因此本文還對基於光纖陀螺的捷聯姿態更新演算法進行了研究。分享友人
