  • Patent number: 6567678
    Abstract: A method for using a multiplex sensor that provides enhanced selectivity and sensitivity. In this method, one or more parameters of a sample are measured by means of multiple spectroscopic techniques, and interferences from physiological and spectral variables are reduced or eliminated. One or more parameters of the sample are measured by means of at least two spectroscopic techniques, wherein the at least two different spectroscopic techniques are selected from the group consisting of: (a) infrared absorbance (b) scattering (c) emission (d) polarization, and (e) photoacoustics.

  • Patent number: 6067463
    Abstract: A method and apparatus for measuring the concentration of an analyte of interest, e.g. glucose, in blood non-invasively, i.e., without penetrating the skin or obtaining a biological sample from the body of a patient. The method and apparatus uses a plurality of measurement channels with appropriate wavelengths of interest to control variations of signal and to separate the contribution of the analyte of interest from those of interfering compounds. The method and apparatus of this invention can also be adapted to allow a portion of a body part to be engorged with blood to bring about greater accuracy in optical measurements. In the method of this invention, at least two similar, but not identical, measurements are made concurrently. For example, at least two measurements can be made with similar, but not identical, wavelengths of electromagnetic radiation. The two wavelengths should not be overlapping to allow maximum non-identity.

  • Patent number: 6064897
    Abstract: A noninvasive Raman sensor and an associated method of measuring at least one parameter of a sample, such as the presence or concentration of an analyte. The sensor includes(a) at least one source of light capable of irradiating the sample with substantially monochromatic light;(b) a filtering module for filtering light scattered by the sample, that includes at least one bandpass filter capable of transmitting two different spectral windows; and(c) at least one detector.The method includes(a) irradiating a sample with light from a source of substantially monochromatic light,(b) collecting light that is scattered by the sample,(c) analyzing the scattered light by passing the light through a filtering module that includes at least one bandpass filter that is transmissive for at least two spectral windows, and(d) detecting light that has been filtered by said filtering module.

  • Patent number: 5788632
    Abstract: An apparatus and a process of determining the concentration of an optically active compound in a biological sample are provided. The process measures the entire polarization state of the sample and compares the measured polarization state of the sample to the polarization state of a sample having a known concentration of that compound. The polarization state of the sample is measured after manipulating the polarization state of light entering and leaving the sample and detecting the light leaving the sample. The apparatus contains a source of light, a sample holder for holding the biological sample, a detector, a first polarization manipulator between the light source and the sample holder, a second polarization manipulator between the sample holder and the detector and an analyzer to correlate detected signals with concentration of the optically active compound.

  • Patent number: 5311013
    Abstract: An optical distribution system incorporating an improved luminescent based optical fiber sensor incorporating a signal generating component for generating a first optical signal, a signal separating component for delivering said first optical signal to the sensor, delivering said second returned optical signal to an associated signal detector, and including signal interference means to separate said first and second signals and minimize cross-talk therebetween. A sensor optical fiber connects a sensor tip to the signal separating component. The signal detector receives a returned signal from the signal separating component and transmits it to a signal-measuring component of the distribution system.

  • Patent number: 4906837
    Abstract: An optical sensor for monitoring the motion and/or position of a moving element. One preferred embodiment of the optical sensor (50) includes a soda lime silicate glass substrate (52) in which a plurality of transmit waveguide channels (54), (56), and (58) are formed by an ion diffusion process. The waveguide conveys light pulses to a plurality of read ports (60), (62), and (64) through which the pulses are emitted to illuminate reflective areas formed on the surface of an adjacent moving element (59). Pulses of light reflected back from the reflective areas re-enter the read ports, propagating in the opposite direction through combination transmit/receive portions of the optical waveguide channels (72), (74), and (76), combining in a common receive waveguide channel (78).
