    摘要: Light sources are provided with enhanced low-frequency (e.g., near infrared) emission. Some disclosed embodiments include a filament and at least one re-radiator element. The filament heats the re-radiator element to a steady-state temperature that is at least one quarter of the filament's absolute temperature. As disclosed herein, the increased surface area provided by the re-radiator element provides enhanced IR radiation from the light source. Patterning or texturing of the surface can further increase the re-radiator element's surface area. Various shapes such as disks, collars, tubes are illustrated and can be combined to customize the spectral emission profile of the light source. Some specific embodiments employ a coating on the bulb as the re-radiator element. The coating can be positioned to occlude light from the filament or to augment light from the filament, depending on the particular application. The various re-radiator elements can be positioned inside or outside the bulb.

    摘要: Various methods and tools optically analyze downhole fluid properties in situ. Some disclosed downhole optical radiometry tools include a tool body having a sample cell for fluid flow. A light beam passes through the sample cell and a spectral operation unit (SOU) such as a prism, filter, interferometer, or multivariate optical element (MOE). The resulting light provides a signal indicative of one or more properties of the fluid. A sensor configuration using electrically balanced thermopiles offers a high sensitivity over a wide temperature range. Further sensitivity is achieved by modulating the light beam and/or by providing a reference light beam that does not interact with the fluid flow. To provide a wide spectral range, some embodiments include multiple filaments in the light source, each filament having a different emission spectrum. Moreover, some embodiments include a second light source, sample cell, SOU, and detector to provide increased range, flexibility, and reliability.
