摘要：本发明涉及用于通过干涉图(具有包含鉴别频率分量的时间变化的频率分量的光束)进行井下光学分析的各种系统和方法。通过在光路中引入干涉仪来产生干涉图，干涉仪的两臂具有以时间为函数变化的传播时间差。光在干涉仪之前或之后与待分析材料相遇，待分析材料例如为来自地层的流体样品、钻孔流体样品、矿样或钻孔壁的一部分。材料的光谱特性会留在光束上，并且可通过执行傅立叶变换以获得光谱或者能够与一个或多个模板相比较的电子处理装置容易地分析所述光谱特性。被设计成在不利的井下环境中良好运行的干涉仪有望实现实验室质量的测量。

摘要： Various systems and methods for performing optical analysis downhole with an interferogram (a light beam having frequency components with a time variation that identifies those frequency components. The interferogram is produced by introducing an interferometer into the light path, with the two arms of the interferometer having a propagation time difference that varies as a function of time. Before or after the interferometer, the light encounters a material to be analyzed, such as a fluid sample from the formation, a borehole fluid sample, a core sample, or a portion of the borehole wall. The spectral characteristics of the material are imprinted on the light beam and can be readily analyzed by processing electronics that perform a Fourier Transform to obtain the spectrum or that enable a comparison with one or more templates. An interferometer designed to perform well in the hostile environments downhole is expected to enable laboratory-quality measurements.

摘要： In a Fourier-transform spectroscopy apparatus, a scanning mirror is arranged on a light path of scanning light. The scanning mirror delays or advances the scanning light with respect to reference light according to the rotational angle of the scanning mirror from its initial position. A spectroscopic spectrum generating unit generates an interferogram based on the intensity of the detection target light obtained from the detection target, and Fourier transforms the interferogram thus generated. The spectroscopic spectrum generating unit corrects the nonlinearity of the group delay between an envelope of the reference light and an envelope of the scanning light, and corrects the nonlinearity of the phase shift between the respective envelopes.

摘要： An interferometer wherein an incident beam from a radiation source hits a beam splitter and is split into a first, reflected partial beam, and a second, transmitted partial beam, that subsequently travel along separate arms of the interferometer. The first and second partial beams are respectively intercepted, reflected, and re-split to form returning beam portions and reflected and transmitted exit beam portions that are recombined to form an exit beam. A second terminal mirror and a folding mirror are associated with the second interferometer arm, and the folding mirror reflects the second partial beam back to the beam splitter along the same path through which it was received. The folding mirror and the second terminal mirror are positioned so that a section of the second partial beam passing back-and-forth between the folding mirror and the terminal mirror crosses the exit beam twice.
