Abstract: An infrared spectrophotometer, which is capable of preventing measurement data measured from being adversely affected by moisture vapor. An internal space of an attachment receiving therein an optical element is sealed and isolated from ambient air by providing a tube and others, and a dehumidifier is provided in the internal space of the attachment for an optical path. Thus, the dehumidifier is disposed in a relatively narrow space, so that the internal space of the attachment can be efficiently dehumidified within a short period of time so as to reduce humidity in the internal space to suppress absorption of moisture vapor which would otherwise occur on the optical path in the internal space of the attachment. This makes it possible to prevent a negative influence of moisture vapor on measurement data, while reducing a standby time due to the dehumidification.

Abstract: 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.

Abstract: A two-beam interferometer for Fourier Transform spectroscopy has a double pivot scanning mechanism. The interferometer has two rigid pendulums that are each rotatable to swing around an associated one of distinct axes of rotation. A linkage links the two rigid pendulums to each other and constrains their rotation relative to each other. The interferometer has bearings, which may be flexure bearings, for rotatably mounting the two pendulums to swing around an associated one of the distinct axes of rotation and a first and a second bearing linking the linkage to an associated one of the pendulums. The two rigid pendulums, the linkage and the bearings can be a monolithic structure.

Abstract: Scanning interferometer and method of using same providing for rapid, reliable detection of chemical compounds that are readily implemented in low-cost, portable configurations for application in a variety of monitoring and detection applications. A scanning double-beam interferometer, particularly a Michelson interferometer, in which the length of at least one of the optical paths (or arms) of the interferometer is selectively adjustable by use of an actuator in which rotational displacement of a rotatable element is converted into linear displacement of at least one reflective surface which forms an end of an optical path of the interferometer is employed to obtain interferograms of electromagnetic radiation attenuated, emitted, scattered or reflected from a sample. The length of the optical path that is adjusted is determined using an optical detection scheme, particularly where marking on the rotatable element are detected to determine linear displacement of the reflective surface.

Abstract: Methods and devices are provided for determining the presence and/or concentration of at least one analyte in a sample of low transmissivity. In the subject methods, a forward beam and a backward beam are produced by or introduced into an interferometer from at least one infrared radiation source. The forward beam is passed into the sample and then collected to produce a sample beam while the backward beam is passed into a reference and then collected to provide a reference beam. The sample and reference beams are recombined either optically into a null beam which is detected at a single detector or electronically nulled after detection on two separate detectors. The presence, and often amount, of at least one analyte in the sample is then derived from the detected null beam. Also provided are devices for practicing the above methods. The subject methods and devices are suitable for use in a variety of different applications, including the detection of the presence, and amount, of one or more blood analytes in a physiological sample, such as blood, tissue or derivatives thereof.
