Abstract: A method and apparatus are provided for the determination of carotenoid antioxidants and similar chemical compounds in biological tissue such as living skin. The method and apparatus provide a noninvasive, rapid, accurate, and safe determination of carotenoid levels which in turn can provide diagnostic information of the antioxidant status of tissue. Reflection spectroscopy is used to measure the concentrations of carotenoids and similar substances in tissue. White light is directed upon the area of tissue that is of interest. A small fraction of diffusively scattered light is collected and measured. The tissue is pressured to temporarily squeeze blood out of the measured tissue volume while the reflection spectrum is continuously monitored, displayed, and analyzed in near real time. After an optimal time period of typically 15 seconds, the influence of the dominating hemoglobin and oxyhemoglobin tissue absorptions on the reflection spectra are minimized.

Abstract: A photo acoustic trace gas detector (100) is provided for detecting a concentration of a trace gas in a gas mixture. The photo acoustic trace gas detector (100) comprises a light source (101), an optical cavity (104a, 104b), ratio modulating means (105, 111) and a transducer (109). The optical cavity (104a, 104b) contains the gas mixture and amplifies light intensity. Maximum amplification is provided when a ratio of a wavelength of the light beam and a length of the optical cavity (104a, 104b) has a resonance value. Ratio modulating means (105, 111) modulate the ratio for transformation of the light beam into a series of light pulses for generating the sound waves, an amplitude of the sound waves being a measure of the concentration of the trace gas. A transducer (109) converts the sound waves into electrical signals.

Abstract: A compact Raman and fluorescence spectroscopy system that uses a microprism or micromirror based optical structure to accomplish the introduction of excitation radiation with compactness and simplified system configuration for portable or mobile spectroscopy applications. A microprism may be glued to a surface location of a focusing lens in the system to directly receive the illumination signal without intervening optical components. Alternatively, the microprism may be simply placed in close physical proximity of the focusing lens without being glued thereto. On the other hand, a micromirror may be used instead of the microprism. The illuminating photons received by the microprism or micromirror may be directly transferred to the sample under investigation via the focusing lens. The compact system may be made portable and may further include an on-board spectrometer with or without a display unit. For chemical detecting applications, a detector (e.g., a CCD array) may also be provided along with the spectrometer.

Abstract: A planar nanospectrometer formed as a single chip that uses diffraction structures, which are combinations of numerous nano-features placed in a predetermined configuration and providing multiple functionalities such as guiding light, resonantly reflecting light at multiple wavelengths, directing light to detectors, and focusing light on the detectors. The diffraction structure can be described as a digital planar hologram that comprises an optimized combination of overlaid virtual sub-gratings, each of which is resonant to a single wavelength of light. Each device includes at least one sensor, at least one light source, and at least one digital planar hologram in an optical waveguide. The device of the present invention allows detection of small amounts of analytes in gases and liquids or on solid surfaces and can be particularly advantageous for field analysis of environmental safety in multiple locations because of its miniature size and low cost.

Abstract: A portable acousto-optical (AO) spectrometer system comprised of at least one AO crystal cell device specially designed for cancellation of side-lobe noise at a desired tuned wavelength of operation. Each AO crystal cell device has a transducer attached and forms an AO tunable filter (AOTF) and forms part of a photo-head assembly. The system can include an optical fiber link between the AO spectrometer photo-head assembly and additional features such as an optical alignment coupling attachment that couple an excitation source such as a laser that operates in either pulse or continuous mode, a probing fiber that provides a hand-held member that can emit a source radiation and in turn observe radiation reflected from an observed sample. There are two embodiment of the AO crystal cell device. Either embodiment of the AO crystal cell design can be used in the system, providing a vibration-insensitive AO spectrometer instrument having high sensitivity, accuracy and resolution capabilities. The types of spectroscopic measurements that can be performed using the invention include fluorescence, Raman, absorption and emission.
