    Abstract: An in-vivo blood composition analyzing apparatus and method generates a laser beam at the blood vessels of the patient's eye. The Raman scattered photons from the blood vessels are collected and used to generate a Raman spectrum indicative of the blood composition. In one embodiment, a laser beam is generated with two streams of photons, the photons of one beam being entangled with the photons of the other beam. One stream is then directed at the eye and only the other beam is analyzed to obtain said Raman spectrum. Alternatively, the scattered photons from the second beam are also analyzed and the results are correlated for greater efficiency and accuracy.

    Abstract: Systems and methods for establishing and/or maintaining the accuracy of a multivariate calibration model designed for quantitative optical spectroscopic measurement of attributes or analytes in bodily tissues, bodily fluids or other biological samples, which are particularly useful when the spectral absorbance of the attribute or analyte is small relative to the background. The present invention provides an optically similar reference sample to reduce the effect of instrument or environment variation on the measurement capability of the model. The optically similar reference can be a gel composition having scattering particles suspended therein. The reference gel can be directly applied to a spectroscopic instrument sampler, or can be in a container specifically designed for optimal coupling to a spectroscopic instrument.

    Abstract: A multi-spectrum image capturing device includes a multi-spectrum illuminating device comprising LED's for emitting lights of different wavelengths from one another, a plurality of optical rods for relaying the lights emitted from the LED's, an optical diffusion element for diffusively reflecting the lights from the optical rods by a white diffusion surface and an aluminum-coated reflecting surface to be irradiated at an angle of about 60° with respect to an image-capturing optical axis, and an optical sheet for further diffusing the lights from the optical diffusion element, and also includes an image-capturing optical system and a CCD for forming an image based on lights reflected from an irradiated surface under illumination by the multi-spectrum illuminating device to capture the formed image. An image output captured by the CCD is analyzed to measure color components of the irradiated surface.

    Abstract: An optical device includes an optical waveguide through which light propagates and a micro-resonator structure including an optical sensor. The micro-resonator is configured to resonate at a wavelength of light that may be transmitted through the optical waveguide. When light at that wavelength is transmitted through the optical waveguide, it resonates in the resonator and is detected by the optical sensor to produce an electrical signal. The optical resonator may be a micro-cylinder, disc or ring resonator and may be coupled to the waveguide via evanescent coupling or leaky-mode coupling. Multiple resonators may be implemented proximate to the waveguide to allow multiple wavelengths to be detected. When the waveguide is coupled to a tunable laser, signals provided by the optical sensor may be used to tune the wavelength of the laser.
