    • One embodiment of the present invention sets forth a technique for determining properties of optical links using the amplified spontaneous emission (ASE) of integrated amplifiers. To calibrate the system, existing amplifiers in the nodes of the system can be operated in an ASE mode. A bypass switch at the mid-stage of each amplifier routes the ASE from the amplifier's first stage into one or more signal processing components, creating reference signals. Subsequently, the bypass switch routes the reference signals back into the mid-stage of the amplifier. After propagating through a link to the next node in the system, the optical parameters of the reference signals are measured and used to determine properties of the link, such as chromatic dispersion and attenuation. Tunable devices within the two nodes connected by the link may be set to compensate for specific properties of the link, thereby improving the quality of transmitted signals.
    • 本发明的一个实施例提出了一种使用放大的放大自发发射(ASE)来确定光链路性质的技术。 要校准系统,系统节点中的现有放大器可以在ASE模式下运行。 每个放大器中段的旁路开关将ASE从放大器的第一级传送到一个或多个信号处理组件,创建参考信号。 随后,旁路开关将参考信号路由到放大器的中间阶段。 在通过链路传播到系统中的下一个节点之后,测量参考信号的光学参数并用于确定链路的属性,例如色散和衰减。 可以设置通过链路连接的两个节点内的可调谐设备来补偿链路的特定属性,从而提高发送信号的质量。

    • A method and system for acquiring seismic data from a seismic survey plan is provided. A survey area is selected in which the seismic data will be acquired. A coordinate for at least one point of interest within the survey area is determined and input into a portable navigation device. A navigation solution is determined between a GPS-determined location of the portable navigation device and the determined coordinate and thereupon presented in a human cognizable media. A seismic device may be positioned at the determined coordinate to insonify a subterranean formation with seismic energy or for detecting reflected seismic energy. Data may be periodically entered into and retrieved from the portable navigation device by an in-field operator. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
