Abstract: An optical method and system sense and identify a foreign particle in a gaseous environment. A light source generates light. An electrically-conductive sheet has an array of holes formed through the sheet. Each hole has a diameter that is less than one quarter of the light's wavelength. The sheet is positioned relative to the light source such that the light is incident on one face of the sheet. An optical detector is positioned adjacent the sheet's opposing face and is spaced apart therefrom such that a gaseous environment is adapted to be disposed therebetween. Alterations in the light pattern detected by the optical detector indicate the presence of a foreign particle in the holes or on the sheet, while a laser induced fluorescence (LIF) signature associated with the foreign particle indicates the identity of the foreign particle.

Abstract: To achieve a given spectral resolution with reduced detector size and commercially available pixel pitches, the Raman spectrum is shifted across the detector array such as by one of the following methods: 1) tuning the excitation wavelength; 2) rotating the grating; 3) displacing the effective input slit (fiber) and acquiring the spectrum under stepped displacement conditions; and 4) displacement of a lens relative to input fiber to displace effective input slit relative to the detector. A composite spectrum is formed and deconvolution of the entrance aperture image and/or pixel masking is then used.

Abstract: A method for determining clinical and/or chemical parameters (S1) in a medium (10), utilizing a laser unit, for emitting coherent light waves (6) and a phototransistor unit, for receiving light waves (8). At least some of the emitted light waves (6) are transferred to the medium (10) and the phototransistor unit waves (8) measures at least some of the light waves (8) that are reflected in the medium (10), the parameters (S1) being determined as a result of the characteristics of the emitted and received light waves (6; 8). The fact that light waves (6) are emitted into the medium (10) by a laser unit (2) and that the light waves (8) that are reflected in the medium (10) are measured by a phototransistor (4) enables the parameters (S1) that occur in the target area of the laser beam to be determined advantageously in a processing and control unit.

Abstract: An apparatus for enhancing the selectivity for spectroscopic measurements of analytes in a turbid medium is described. In one example, spatial filters are used to select only certain radii from the medium to be imaged. This selection is accomplished by placing an optical obstruction on the surface of the medium or at an image plane of the surface later in the optical imaging system. In one implementation, this is achieved by placing a fiber bundle at an image plane of the collecting optical system and then using a spacer of appropriate size at the center of the fiber bundle to act as a central obstruction.
