Abstract: The invention comprises a method of adapting derivative spectrometry for use in a downhole environment and addresses problems that are inherent in this environment. Such problems include, but are not limited to, elevated temperatures and scattering from particles residing within dirty fluid samples. Under such conditions, the photometric resolution of a spectrometer decreases at the same time that the need for better resolution increases. The invention improves the resolution by measuring the first derivative of the spectrum. The derivative spectrometer of this invention operates by vibrating a linear variable interference filter back and forth along the plane of the filter or by oscillating a circular variable filter about some angle. The effect is to oscillate the wavelength of light that is received by each photodetector. The photodetector signal can be electronically filtered to reject signals that are not at the oscillation frequency and which do not have a fixed phase relative to it. In a preferred embodiment, a vibrating actuator is the means to achieve the required oscillations about a given wavelength. Derivative spectrometry gives a higher resolution than normal methods of spectrometry. Through improved resolution, it is possible to estimate the contamination percentage of the crude oil in real time. Furthermore, it is possible to determine whether a contamination percentage is leveling off over time. It is expected that high-resolution spectra enable an improved estimation of the percentages of methane (natural gas), aromatic, olefins, saturates, and other crude oil properties.

Abstract: A fluorescence spectrophotometer having an excitation double monochromator, a coaxial excitation/emission light transfer module, and an emission double monochromator. Each monochromator includes a pair of holographic concave gratings mounted to precisely select a desired band of wavelengths from incoming broadband light without using other optical elements, such as mirrors. Selected excitation light is directed into a sample well by a light transfer module that includes a coaxial excitation mirror positioned to direct excitation light directly to the bottom of a well of a multi-well plate. Fluorescence emission light that exits the well opening is collected by a relatively large coaxial emission mirror. The collected emission light is wavelength selected by the emission double monochromator. Selected emission light is detected by a photodetector module.

Abstract: A wavelength variable light source emits a light whose wavelengths continuously change from a preset start wavelength up to a stop wavelength to a measuring object. A timing information output section generates timing information showing emission timings of lights emitted from the wavelength variable light source and having start and stop wavelengths and a plurality of wavelengths obtained by delimiting the wavelengths between the start and stop wavelengths in predetermined steps. A light receiving section receives the light output from the measuring object and outputs a signal showing a measured value of a received light. A plurality of amplifiers receive the signal output from the light receiving section and amplify the signal at each predetermined amplification factor. A signal selecting section selects one signal kept in a predetermined measuring range of signals amplified by the plurality of amplifiers at the each predetermined amplification factor and outputs the one signal as a measured value of a light of a wavelength decided in accordance with corresponding timing information in the information output from the timing information output section.

Abstract: For calibrating a spectrophotometer having a monochromator with a rotary mechanism to rotate a diffraction grating for producing a monochromatic beam of light of a specified target wavelength, transmission errors by the rotary mechanism are preliminarily measured to obtain an error curve having peaks corresponding to feed angles. A smallest angular interval, greater than an allowable limit, between a pair of feed angles corresponding to a mutually adjacent pair of peaks in the error curve is selected. One or more lamps emitting bright lines with wavelength interval which corresponds to motion of the rotary mechanism by less than one half of the selected smallest angular interval are used as a light source. Control values to be supplied to the rotary mechanism for obtaining monochromatic beams of light from the bright lines emitted from the selected lamps are determined by measurements. A calibration table, from which a required control value corresponding to a specified wavelength value can be retrieved, is produced from these control values and wavelength values of the bright lines and is stored in a memory device.

Abstract: In its preferred embodiment, a scanning monochromator uses a pulse-driven micro-stepping motor to drive a spectral-dispersion element via a reduction-gear harmonic drive. The motor is directly coupled to the input hub of the reduction-gear drive, and the output hub of the reduction-gear drive directly supports the spectral-dispersion element. By selecting a motor with a great number of steps per revolution, and a harmonic drive with a great reduction ratio, a resolution of 5 million pulsed steps is available, per single rotation of the output hub of the reduction-gear drive. This translates into more than 600,000 incremental angular-displacement steps over a usable 45.degree. range of dispersion-element rotation.

Abstract: An optical scanning device, such as a chromatoscanner, includes a spectroscope having a rectangular outlet slit for producing a light beam in the shape thereof. A rotatable disk having a spiral slit is disposed in the path of the light beam to produce light pulses along radial lines of the disk which are directed to the surface of a specimen. The absorbancy of the light pulses at discrete positions of the specimen is measured and stored in a memory in accordance with the corresponding location on the specimen as derived from measuring the rotation angle of the disk.
