Abstract: A SWIR hyperspectral imaging filter has serial stages along an optical signal path with angularly distributed birefringent retarders and polarizers. The retarders can include active retarders such as tunable liquid crystal birefringent elements, passive retarders such as fixed retarders, and/or combinations thereof. Distinctly different periodic transmission spectra are provided by different filter stages, each having multiple retarders, in particular with some stages having broad bandpass peaks at wide spectral spacing and other stages have very narrow closely spaced peaks. The respective spectra include at least one tunably selectable band at which the transmission spectra of the filter stages coincide, whereby the salutary narrow bandpass and wide spectral spacing ranges of different stages apply together, resulting in a high finesse wavelength filter suitable for spectral imaging. The filter may be configured to provide faster switching speed and increased angle of acceptance and may operate in the rage of approximately 850-1700 nm.

Abstract: An arrangement adapted for a spectral analysis, having a light transmitting means, a delimited space in the form of a cavity serving as a measuring cell and defining an optical measuring distance, a light sensing means for detecting radiation passing said optical measuring distance from said light transmitting means, and a unit, connected at least to said light sensing means and performing the spectral analysis. Beams of radiation from the light transmitting means are made to pass through an optical band-pass filter at different angles of incidence. The filter is structured so as to pass a wavelength in dependence of the angle of incidence. A first chosen wavelength component is separated from a second wavelength component, each being received in its opto-electric means. Said unit is adapted for detecting and calculating an occurring radiation intensity for each such wavelength component.

Abstract: The present invention provides a simple, robust, and versatile high-resolution spectrometer that is suitable for downhole use. The present invention provides a method and apparatus incorporating a spinning, oscillating or stepping optical interference filter to change the angle at which light passes through the filters after passing through a sample under analysis downhole. As each filter is tilted, the color or wavelength of light passed by the filter changes. Black plates are placed between the filters to isolate each filter's photodiode. The spectrometer of the present invention is suitable for use with a wire line formation tester, such as the Baker Atlas Reservation Characterization Instrument to provide supplemental analysis and monitoring of sample clean up. The present invention is also suitable for deployment in a monitoring while drilling environment. The present invention provides a high resolution spectometer which enables quantification of a crude oil's percentage of aromatics, olefins, and saturates to estimate a sample's gas oil ratio (GOR). Gases such as CO2 are also detectable. The percentage of oil-based mud filtrate contamination in a crude oil sample can be estimated with the present invention by using a suitable training set and chemometrics, a neural network, or other type of correlation method.

Abstract: A variable bandwidth tunable optical filters comprised of two transparent optical substrates, upon each of which is deposited a linearly variable multilayer interference filter coating which varies in total thickness from end to end in a wedged fashion. This wedge imparts a corresponding variation of the center wavelength of the filter bandpass with respect to the linear position of the coated filter substrates. The variable bandpass tunable filter can be adjusted to a specific center wavelength by moving the filter pair together linearly through the incident beam. The bandwidth of the filter pair is maximized when the two filters are spectrally aligned, and is determined by the bandwidth of the individual filters. The variable bandwidth of the tunable filter can be adjusted by introducing a relative linear offset between the linearly variable filter pair.
