    Abstract: An instrument and method for measuring light or color using modulated illumination. The system includes an LED illuminator modulated at a specific frequency for illuminating the sample, and a sensor capable of differentiating between the modulated light from the sample and unmodulated ambient light. The instrument is therefore capable of “seeing” only light from the sample, while ignoring ambient light. In a second embodiment, the system includes multiple illuminators of different colors each modulated at a unique frequency so that the sample can be measured at multiple at each of the different frequencies.

    Abstract: A method and apparatus for automatically selecting test types for an analytical meter system based on the insertion into the meter of a test element. The test element can be an analytical element, formed by a test strip with a fluid such as blood applied thereto; a control element, formed by a test strip with control fluid applied thereto; or a standard element, or a standard strip exhibiting known optical properties. By inserting the test element into the analytical meter system, optical properties are measured and the existence of relationships between the measurements are ascertained. Based on the existence or nonexistence of certain relationships, the proper test can be automatically selected by the meter without the need for user interaction. Advantageously, the results of the test can be classified and stored according to test type.

    Abstract: An instrument for chemical spectroscopy with imaging capabilities. A lightsource produces an array of light beams, each of which is made up of a plurality of discrete wavelengths. The array of light beams are modulated by an interferometer, then directed through a sample to an array of detectors. The sample may be a chemical mixture (e.g. a fuel stream in a manufacturing facility) or a body part (e.g. breast, limb, or head). An array of laser or light-emitting diodes provides light at the desired wavelengths and high intensity. The set of wavelengths is selected for a particular kind of analysis, and a specific set of possible absorbing species to be detected. The different wavelengths are guided optically (using fiber optics, lenses, and/or mirrors) into a single lightbeam, or an array of lightbeams. This light is then directed through the sample and onto a detector. The lightsource and detector, or lightsource alone, may be rastered if necessary to form an image. Individual lightbeams in an array may be modulated, polarized, or both so as to improve resolution. The signal from the detector undergoes a Fast Fourier Transform to produce a near-infrared absorption spectrum as a function of wavelength. The absorption spectra can be used to produce an image of the spacial distribution of detected species within the sample. Either the lightsource or detectors can be placed on the end of a probe or catheter for imaging through the wall of a hollow sample.
