    Abstract: In a measuring probe 40, a measuring beam is diffused by a first diffusion plate 19, and when received by a plurality of light-receiving sensors 13B, 14B, 15B via a plurality of interference filters 13A, 14A, 15B, the measuring beam is made incident on the interference filters 13A, 14A, 15B via second diffusion plates 13C, 14C, 15C. Those interference filters 13A, 14A, 15B are formed such that transmittance characteristics corresponding to a measurement parameter are obtained correspondingly to intensity distribution conditions for an angle of incidence of light incident on the interference filters 13A, 14A, 15B. Therefore, the measuring probe 40 can reduce the effect of displacement of the transmission characteristic caused by the angle of incidence, while using the interference filters 13A, 14A, 15B.

    Abstract: A tool for measuring properties of a formation fluid downhole within a wellbore is described. The tool comprises a port for obtaining a sample of fluid downhole and a spectroscope. The spectroscope includes an adaptive optical element, a light source, and at least two detectors. The adaptive optical element is capable of directing a first wavelength band along a first light path and a second wavelength band along a second light path when both said bands are simultaneously incident thereon. The spectrum of the light source is spectrally dispersed across the adaptive optical element in such a way that a first wavelength band is directed along the first light path, through the sample, and to one of the detectors, and a second wavelength band is directed along the second light path to a second of said at least two detectors.

    Abstract: A system for the detection of components in a region of the atmosphere is disclosed, the system comprising a spectrometer assembly having a detector optically coupled to a optical assembly, the optical assembly receiving incident sunlight from the region of the atmosphere, the optical assembly having a field of view extending from the zenith to below the horizon; means for rotating the spectrometer assembly about a vertical axis; and a processor for receiving data from the spectrometer assembly and compiling data relating to the identity and concentration of components in the region of the atmosphere. A method of monitoring pollutants in a region of the atmosphere comprises providing a spectrometer assembly having a detector optically coupled to an optical assembly having a field of view extending from the zenith to below the horizon; exposing the spectrometer assembly to incident sunlight while rotating the spectrometer assembly about a substantially vertical axis; and processing signals received from the spectrometer assembly to analyse components in the atmosphere. The system and method are particularly useful in monitoring atmospheric pollutants arising from the combustion of hydrocarbon fuels, in particular oxides of nitrogen and/or sulphur. A preferred arrangement comprises a plurality of systems disposed at spaced apart locations and having their scanned regions overlapping.

    Abstract: Provided is a tunable filter including: a polarization splitter that splits input light into two linearly polarized light rays of mutually orthogonal vibration directions; a wavelength dispersion spectroscopic element that splits the two linearly polarized light rays split by the polarization splitter, into two spectral images having spatial spread in one direction, the two spectral images corresponding to the two linearly polarized light rays; and a reflective spatial modulator device that modulates and reflects linearly polarized light in each wavelength region for the two spectral images independently from each other, where modulated light reflected at the reflective spatial modulator device reenters the wavelength dispersion spectroscopic element and the polarization splitter, thereby splitting and outputting the modulated light, as output light in a wavelength region modulated by the reflective spatial modulator device and output light in a wavelength region not modulated, and input light and reentered light to the polarization splitter and input light and reentered light to the wavelength dispersion spectroscopic element are parallel light fluxes.
