Abstract: Method for identification of plastic materials of interest by spectroscopic measurements, comprising the steps of measuring a sample and providing a sample spectrum; providing reference spectra for a given group of reference materials of interest, determining spectral distances between sample spectrum and reference spectra, material identification by associating the sample to the material having the reference spectrum with the smallest spectral distance to the sample spectrum. In this method a multi-level measurement is conducted, wherein in each level the number of possible materials is further limited. In a first level at least 2 sub-groups and in all levels starting with a second level at least one sub-group of possible materials are defined, wherein one sub-group in the first level comprises all possible materials that are easily distinguishable and at least one further sub-group in the first level comprises materials that are difficult to distinguish from each other. To each sub-group at least one identification frequency range is associated, and said spectral distances are only determined within said at least one identification frequency range in each relevant sub-group of each level and only with respect to reference spectra of materials being comprised in the relevant sub-group.

Abstract: A spectroscopic analyzing arrangement comprises an ATR optical sampling plate with a front sample-contacting face and an opposed rear internally face. An anvil assembly is arranged so that the sample-contacting face can be pressed against the sample to receive spectroscopic information. A reflection barrier between the anvil assembly and the rear face prevents internally reflected light within the sampling plate from picking up spectroscopic information from the anvil assembly, thus enhancing the performance of the arrangement.

Abstract: A multispectral imaging system (1) and method utilize an optical processor (3) for simultaneously comparing an input wavelength spectrum observed in a single spatial pixel in a scene image from a multispectral imager (2) with a plurality of template wavelength spectra to find a correlation. The optical processor exploits the three-dimensional attributes of optical correlation to perform massively parallel correlation processing by modulating (4) respective ones of a plurality of spectral bands of the input wavelength spectrum of an incident light beam (6) with modulating elements (5) to alter at least one property of the incident light beam by a value corresponding to the observed intensity of the input spectrum in the respective spectral band. In a disclosed embodiment, the modulated beam is expanded and transited through a spatial light modulator (7) having a two-dimensional array of modulating elements. Each row of the elements of the array alter the at least one property of the incident light by values corresponding to a particular template wavelength spectrum of a plurality of template wavelength spectra of the modulator. The values corresponding to each template spectrum are the conjugates of the representative values of the modulating elements of the template spectrum of the plurality of template spectra.

Abstract: A silver halide fiber optic for the detection and identification of petroleum. The fiber optic serves both as a waveguide for transmitting a signal to and from petroleum in remote locations and also as an intrinsic part of the sensing element to obtain evanescent wave spectra. The evanescent wave is attenuated at various wavelengths based on the chemical composition of the petroleum in which the sensor is immersed. The spectrum obtained from an unknown sample is compared with the spectrum of known samples from a library to identify the unknown sample.
