Abstract: An optical detector for spectroscopic analysis of a substance within a given spectrum has a first resolution at a first part of the spectrum (101,102) and a second resolution, different from the first resolution, at a second part of the spectrum, different from the first part of the spectrum. High resolution may be used at the important parts of the spectrum only, which thus results in less overall resolution. The detector may be used in a non-invasive glucose detection system having non-equally distributed spectral resolution.

Abstract: In one general aspect, a spectroscopic method for monitoring heterogeneity of a sample is disclosed. In this method, sampled spectroscopic measurements are acquired over a range of different micro locations in a macro-sample of the sample. This step is repeated for micro-locations in further macro-samples of the sample, and a statistical measure of chemical heterogeneity is derived from the acquisitions. In another general aspect, differently sized samples are acquired, and a statistical measure of chemical heterogeneity is derived from these acquisitions.

Abstract: A tunable transmissive grating comprises a transmissive dispersive element (1), a reflective element (2) and an angle ϑ formed between the two elements. A first optical path is formed according to the angle ϑ, wherein light dispersing from the dispersive element is directed onto the reflective element and reflects therefrom. At least one element is rotatable about a rotational center (6) to cause a second optical path and thereby tune the wavelength of the light reflecting from the reflective element. Both elements can be rotatable together around a common rotational center point (6) according to certain embodiments, and/or each element can be independently rotated around a rotational axis associated only with that element. According to some embodiments, the relative angle ϑ formed between the elements is held constant; however, in other embodiments ϑ can vary. A control system can be used to operate the device.

Abstract: The present invention provides a simple, robust, and versatile high-resolution spectrometer that is suitable for downhole use. A method and apparatus are provided incorporating a spinning, oscillating or stepping optical interference filter (109) to change the angle at which light passes through the filter(s) after passing through a sample (105) under analysis downhole. As each filter is tilted, the color or wavelength of light passed by the filter changes. Black plates (111) are placed between the filters to isolate each filter's photodiode (113). The spectrometer is suitable for use with a wire line formation tester. The invention is suitable for deployment in a monitoring while drilling environment. A high resolution spectrometer is provided which enables quantification of a crude oil's percentage of aromatics, olefins, and saturates to estimate a sample's gas oil ratio. The percentage of oil-based mud filtrate contamination in a crude oil sample can be estimated.
