Abstract: The present invention refers to an arrangement ('C') adapted to evaluate the spectral intensity of and/or a changing in the spectral intensity of an electro-magnetic beam (1) or a bundle of beams (2), whereby said bundle of beams is directed towards and received by a lens element (3a) and where said lens element (3a) is adapted to direct said bundle of beams towards a multitude of electro-magnetic beam to an electric signal transforming means (4), named as an opto-electric transforming means, said means adapted to generate an electric signal (5) representative to said spectral intensity of or said changing in said spectral intensity of said beam (1, 2). The invention suggests that a multitude of lens elements (3, 3a) shall expose dimensions adapted within a sub-micron scale (10-6m) and that at least one of said opto-electric transforming means (4), preferably a multitude of said means (4), is arranged adjacent to said lens element (3a).

Abstract: Weak signals scattered from analytes at multiple wavelengths can be summed to illuminate either a single detector or a multiplicity of detectors, offering the possibility of concentrating the spectral energy on a smaller total detector area. In addition, a method is disclosed whereby a calibration of the resulting signal for a given analyte can be obtained by means of measuring the quantity of water in the sample volume and by means of measuring the salinity of the fluid in the sample volume.

Abstract: An imaging system comprising a lens, a detector array (e.g., focal plane array), a signal processing module and a shutter, wherein the shutter is positioned in front of the lens (between the lens and the scene being imaged). This front lens shutter mount configuration allows offset correction to compensate for internal radiant flux and other deficiencies associated with conventional systems.

Abstract: A spectrophotometric instrument including light signal sources, a detector, a processor/controller, a probe and a calibration device. The light signal sources have measurement light wavelengths and a calibration detection wavelength. The probe has one or more send fibers coupled to the measurement and calibration light signal sources for transmitting the light signals into tissue, and one or more receive fibers for receiving light including the measurement light signals and the calibration light signal. The calibration device is adapted to receive the probe and has an optical filter for transmitting the measurement light signals but not the calibration light signal. The detector is coupled to the receive fibers to generate electrical signals representative of the light received at the receive fibers. The processor/controller is coupled to the detector and initiates a calibration procedure when the calibration light signal is not detected.

Abstract: An individualized modeling equation for predicting a patient's blood glucose values is generated as a function of non-invasive spectral scans of a body part and an analysis of blood samples from the patient, and is stored on a central computer. The central computer predicts a blood glucose value for the patient as a function of the individualized modeling equation and a non-invasive spectral scan generated by a remote spectral device. If the spectral scan falls within the range of the modeling equation, the predicted blood glucose level is output to the patient. If the spectral scan falls outside the range of the modeling equation, regeneration of the model is required, and the patient takes a number of noninvasive scans and an invasive blood glucose level determination. The computer regenerates the individualized modeling equation as a function of the set of spectral scans and corresponding blood glucose values.

Abstract: Illuminators and systems are provided that permit the production of a beam of electromagnetic radiation having a selected peak wavelength band width, intensity, pulse frequency and pulse duration for a variety of analytical and therapeutic applications. The multiple beam illuminators (100) use filter elements arranged into filter arrays (309-311), having characteristic wavelength absorption. By providing a series of filter arrays (220) formed into a tracks having defined wavelength offsets, radiation passing through a portion of a track can be modified to include selected wavelength and bandwidth. Selection of a peak wavelength(s) and bandwidth can be accomplished using mechanical interrupter (152), mechanical shutter (1708), or electro-optical device (2000) including liquid crystal device. Multiple output beams (132,136) permit the coordinated illumination of a target, and sensors (601a-601c) provide feedback regarding the effects of illumination of the target. Computer storage devices (606), programs (604), and controllers (603) can provide easy selection of the characteristics of the output beams. Output beams (605) can have a variety of different shapes and configurations, depending on the desired application.

Abstract: Encoded spatio-spectral information processing is performed using a system having a radiation source (12), wavelength dispersion device (16) and two-dimensional switching array (18), such as digital micro-mirror array (DMA). In one aspect, spectral components from a sample (24) are dispersed in space and modulated separately by the switching array, each element of which may operate according to a predetermined encoding pattern. The encoded spectral components can then be detected and analyzed. In a different aspect, the switching array (18) can be used to provide a controllable radiation source for illuminating a sample (24) with radiation patterns that have predetermined characteristics and separately encoded components. Various applications are disclosed.
