Abstract: A device implements a method for detecting contamination of an FTIR-based panel. The apparatus generates projection signals representing detection lines that have propagated on a plurality of propagation paths by total internal reflection (TIR) inside a transmissive panel such that contamination on the panel surface causes attenuation (frustration) of at least one of the projection signals. The device generates a transmission value for each detection line in the transmissive panel, and determines the presence of contamination on the surface of the panel by comparing the transmission values according to at least one of the presented comparison techniques.

Abstract: The invention relates to a method of controlling a product analysis spectrometer, the spectrometer comprising a light source (LS) comprising several light-emitting diodes (LD1-LD4) having respective emission spectra covering in combination a band of analysis wavelengths, the method comprising steps consisting in: providing a supply current (I1-I4) to at least one of the light-emitting diodes so as to illuminate it, measuring a luminous intensity (LFL1- LFL4) emitted by the light source by measuring a current at a terminal of at least one other of the light-emitting diodes which is kept unlit, determining as a function of each measurement of luminous intensity a setpoint value (LC1-LC4) of the supply current for each lit diode, and regulating the supply current for each lit diode so that it corresponds to the setpoint value.

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.

Abstract: A method of normalizing an analyzer response value of a fluorescence analyzer is provided. The method includes measuring an excitation spectrum of the analyzer and measuring an emission sensitivity spectrum of the analyzer. Next, a normalization factor based at least in part upon the excitation spectrum of the analyzer and the emission sensitivity spectrum of the analyzer is determined. The sample is then analyzed to obtain an uncorrected analyzer response value. A normalized analyzer response value is calculated based at least in part upon the uncorrected analyzer response value and the normalization factor.

Abstract: In a method for transilluminating objects, the objects are illuminated and transmitted light is being received by a light detector. The objects are illuminated by a light bundle having an elongate cross section, and light source and objects are moved relative to each other, whereby the objects are successively transilluminated. The local intensity of the transillumination light source along the longitudinal direction of the cross section is preferably controllable, and it is preferably controlled in dependency of the extension of the objects for the attainment of reduced variation of the intensity of the transillumination light incident onto the light detector.
