摘要： An acousto-optic frequency shifter in which two cylindrical acoustic resonators driven 90.degree. out of phase from one another are placed around a birefringent, single-mode optical fiber approximately three-quarters of a polarization beat length apart. The resonators interact with optical radiation propagating in one of two polarization modes of the fiber, the first to cross-couple two sidebands into the other polarization mode, and the second to suppress one of the sidebands in the cross-coupled mode and enhance the other, thereby creating a single sideband signal completely within the fiber.
摘要翻译：一个声光移频器，其中相互驱动90°异相的两个圆柱形声谐振器被放置在双折射单模光纤周围大约四分之三的偏振拍子长度。谐振器与在光纤的两个偏振模式中的一个中传播的光辐射相互作用，首先将两个边带交叉耦合到另一个偏振模式，第二个将交叉耦合模式中的一个边带抑制，并增强另一个，从而在光纤内完全产生单个边带信号。

摘要： A method and apparatus, utilizing multiple light signals, for extending the dynamic range of an interferometric system such as an optical fiber gyroscope based on dual wavelength measurement of the Sagnac phase shift in order to determine the fringe number of the interferometric fiber system, thereby increasing the unambiguous range of the device. An analogue measure of the fringe number is provided, thus eliminating the need for digital fringe counting or tracking. An apparatus is described for measuring absolutely, within certain upper bounds determined by the exact wavelengths used, the rotation rate when the system is powered up in a rotating frame.
摘要翻译：一种利用多个光信号的方法和装置，用于扩展基于Sagnac相移的双波长测量的诸如光纤陀螺仪的干涉系统的动态范围，以便确定干涉光纤系统的边缘数，从而增加设备的明确范围。提供了条纹数字的模拟测量，从而消除了对数字条纹计数或跟踪的需要。描述了一种用于在由所使用的精确波长确定的某些上限内绝对测量当系统在旋转框架中通电时的旋转速率的装置。

摘要： A method of aligning the polarization-preserving axis of a receiving end of a polarization-preserving optical fiber with the linearly-polarized output of a semiconductor laser in which the fiber optic end is placed substantially adjacent the laser rather than being separated from the laser by a polarizing optical system.
摘要翻译：将偏振保留光纤的接收端的偏振保持轴与半导体激光器的线偏振输出对准的方法，其中光纤端基本上与激光器相邻放置，而不是通过偏振光学系统。
