摘要： The number of sensors that can be used by an SSA system including a single source can be increased by using a multi wavelength source to send different wavelength pulses to each of a plurality of different sensor array ladders, particularly Sagnac sensor array (SSA) ladders. More particularly, each broadband pulse from a broadband source is wavelength divided into a plurality of narrower pulses with each narrower pulse being used in a separate sensor array ladder.

摘要： A proof mass is suspended in a cavity in a housing. The proof mass moves along a sensing axis in response to linear acceleration. Elastic support members are connected between the proof mass and the housing and are arranged to exert a reaction force on the proof mass in response to displacement of the proof mass along the sensing axis. An optical fiber is connected between the proof mass and opposite sidewall portions of the housing such that displacement of the proof mass along the sensing axis elongates a first portion of the optical fiber and shortens another portion. An optical signal source provides a broadband optical signal input to the optical fiber. A fiber optic Bragg grating is formed in the optical fiber and arranged to reflect a portion of the optical signal. Acceleration of the proof mass modulates the wavelength of the reflected optical signal.

摘要： In tunable systems, during a tuning cycle, express channels or wavelengths are dropped as the system sweeps through its free spectral range (FSR) before stopping at the desired wavelength to be dropped. This is disadvantageous as the data information in the express wavelengths suffers a hit or momentary increase in bit error rate (BER). Techniques for eliminating or at least minimizing interference to those channels or wavelengths are disclosed. According to one aspect of the present invention, the wavelength selection to be dropped is done “off-line” and does not affect the express channels. An optical reference source is used to set up and tune a drop filter. Once the filter is set to the appropriate dropping wavelength, a secondary filter is scanned to cause the channels to be shunted to the drop filter. If the wavelength of a signal and the drop filter matches, the signal is dropped. If the wavelength of the signal and the drop filter wavelength do not matches, the signal passes and is recombined with the other express channels.
摘要翻译：在可调系统中，在调谐周期期间，随着系统在其所需波长停止之前扫描其自由光谱范围（FSR），表示通道或波长被丢弃。这是不利的，因为表达波长中的数据信息遇到比特错误率（BER）的命中或瞬间增加。公开了用于消除或至少最小化对这些通道或波长的干扰的技术。根据本发明的一个方面，要丢弃的波长选择是“离线”完成的，并不影响快速通道。光学参考源用于设置和调整下降滤波器。一旦滤波器被设置为适当的下降波长，则扫描次级滤波器以使通道被分流到放大滤波器。如果信号的波长和下降滤波器匹配，则信号被丢弃。如果信号的波长和下降滤波器波长不匹配，则信号通过并与其他快速通道重新组合。

摘要： Optical fiber coils are formed on inner and outer mandrels. The inner mandrel is spaced apart from the outer mandrel to form a cavity between them with the inner fiber coil being inside the cavity. Water-tight seals between the inner and outer mandrels keep the inner coil isolated from underwater acoustic waves that may be incident upon the outer coil. The optical fibers are included in a dual optical path fiber optic interferometer that includes the inner fiber coil in a first optical path and the outer fiber coil in a second optical path. A central wall divides the inner region of the inner mandrel into two cavities. A tie rod has a first end connected to the wall and a second end extending out of the first cavity in the inner mandrel. A backshell is connected to the second end of the tie rod. The backshell includes a hollow portion formed as a housing for protecting fiber optic components of the interferometer.

摘要： An omnidirectional fiber optic hydrophone includes a concentrically-arranged pair of ring-shaped mandrels mounted between planar upper and base members. Each of the rings is formed of inner and outer annular portions separated by an annular void. Optical fibers wound about the outer circumference of the outer annular portion of the outer ring and about the outer circumference of the inner annular portion of the inner ring communicate with a source of optical energy and with a photodetector to provide signals for measuring acoustic wave-induced deflections of the rings. A plurality of mandrels may be employed in a single hydrophone which may be potted with elastomeric material or free flooded.
