摘要
介绍光学工程在光测量和光纤通信中的运用及未来的发展趋势。光测量主要通过激光发生干涉(衍射),利用干涉(衍射)条纹的级次进行定标、精确测量,利用零级条纹色偏最小原理,对条纹级次进行自动判断;利用光脉冲的高次谐波,测量电场。光通信主要介绍了相干光通信技术、波分复用技术、拉曼光放大器、及全光网络。
This paper focuses on the application and the new trend of Optical Engineering in the optical measurement and optical fiber communication. In optical measurement, we could calibrate precision instrument and increase the measuring precision by using the laser interference （diffraction） fringe orders; the fringe orders could be automatically determined by the zero order fringes＇ minimum chromatic polarization; and the electric filed can be measured through higher harmonic scales. In terms of optical communication, coherence optical communication technique, wavelength division multiplexing technique, Raman optical amplifier, and the All Optical Networks are discussed in this paper.
