    Abstract: A system and method are provided for utilizing section contribution characteristic data to achieve accurate measurements by compensating for unwanted phosphor output variations that occur at specific sections of phosphor on a rotating high intensity phosphor point source element. Phosphor grain size, density, blend homogeneity, or illumination gap variations may cause the unwanted variations. Based on the section contribution characteristics, excitation energy compensation may provide a stable output illumination spectrum or computational compensation may correct measurements for effects arising from predictable output illumination spectrum variations. The section contribution characteristic data may comprise section wavelength intensity profile data and/or section efficiency data, in various embodiments. In some embodiments, the sections may be on the order of the size of the phosphor grains and may be characterized and compensated. The sections may include phosphor blends, or distinct phosphor types, in various embodiments.

    Abstract: A frequency comb laser providing large comb spacing is disclosed. At least one embodiment includes a mode locked waveguide laser system. The mode locked waveguide laser includes a laser cavity having a waveguide, and a dispersion control unit (DCU) in the cavity. The DCU imparts an angular dispersion, group-velocity dispersion (GVD) and a spatial chirp to a beam propagating in the cavity. The DCU is capable of producing net GVD in a range from a positive value to a negative value. In some embodiments a tunable fiber frequency comb system configured as an optical frequency synthesizer is provided. In at least one embodiment a low phase noise micro-wave source may be implemented with a fiber comb laser having a comb spacing greater than about 1 GHz. The laser system is suitable for mass-producible fiber comb sources with large comb spacing and low noise. Applications include high-resolution spectroscopy.

    Abstract: A system for determining an analyte concentration in a fluid sample (e.g., glucose) comprises a light source, a detector, and a central processing unit. The detector is adapted to receive spectral information corresponding to light returned from the fluid sample being analyzed and to convert the received spectral information into an electrical signal indicative of the received spectral information. The central processing unit is adapted to compare the electrical signal to an algorithm built upon correlation with the analyte in body fluid. The algorithm is adapted to convert the received spectral information into the analyte concentration in body fluid. Spectral information is delivered from the central processing unit to the light source and used to vary the intensity and timing of the light to improve the accuracy of conversion into analyte concentration.

    Abstract: An improved apparatus and method for fluorescence subtraction in Raman spectroscopy, where a narrow band light source and a broad band light source are utilized to stimulate Raman scattering and fluorescence emission from the same subject to produce two Raman/fluorescence spectra. The two light sources, with matched output power, produce similar level of fluorescence emission, yet the Raman scattering signal produced by the broad band light source has much lower spectral intensity than that produced by the narrow band light source. By subtracting the two Raman/fluorescence spectra, the weak Raman signal can be extracted from a strong fluorescence background.
