Abstract: PURPOSE:To elevate the measuring accuracy of precise spectrophotometry while reducing the measuring time, by optically separating primary diffracted light and the secondary diffracted light obtained from a diffraction grating to draw them from different emission slits. CONSTITUTION:Radiation introduced from an incident slit 6 is introduced to a collimator/mirror 8 with a flat mirror 7 to form an image on a diffraction grating 1. The diffracted light 4 leaving the grating 1 is made incident into a cold mirror 9, for example, at an incident angle 45 deg.. When radiation is incident into the mirror 9 at 45 deg. to the normal, the mirror 9 is so arranged to allow the transmission of radiation with the wavelength of above 1,000nm while reflecting that therebelow to separate the optical path into the primary diffracted light 10 and the secondary diffracted light 11. The primary diffracted light 10 is introduced with a focusing mirror 12 and a flat mirror 13 to form an image of an incident slit 6 created by the diffracted light is formed on a first emission slit 14. The higher order of diffracted light 11 is introduced with a focusing mirror 15 and a flat mirror 16 to form an image of the emission slit 6 created by the diffracted light on a second emission slit 17.

Abstract: Light of two different wavelengths is passed through or reflected from a member of the body so as to be modulated by the pulsatile blood flow therein. The amplitudes of the alternating current components of the logarithms of the respective light modulations are compared by taking their molecular extinction coefficients into account so as to yield the degree of oxygen saturation. By adding a third wavelength of light, the percentage of other absorbers in the blood stream such as a dye or carboxyhemoglobin can be measured. Fixed absorbers reduce the amount of light that passes through or is reflected from the body member by a constant amount and so have no effect on the amplitudes of the alternating current components that are used in making the measurements.

Abstract: Methods and optical detection systems (200, 300, 800, 900) for generating and processing a real-time time-domain cavity ringdown spectroscopy (CRDS) signal (831, 931) from an absorbing species in an optical detection system (200, 300, 800, 900) having an optical ringdown cavity (200, 300) are disclosed. The optical ringdown cavity (200, 300) is adapted for accepting a sample of an absorbing species. One or more modulated light signals (241,243,245,341) are generated using one or more light sources (240, 242, 244, 340). The light source(s) (240, 242, 244, 340) is pulsed at a specified pulse rate(s). The modulated light signal(s) (241,243,245, 341) is resonated using the optical ringdown cavity (200, 300) comprising a plurality of mirrors(220, 230), or sets of mirrors (320, 330), to produce the CRDS signal (831, 931). The reflectivity of the mirrors (220, 230), or sets of mirrors (320, 330), is dependent upon the pulse rate of the modulated light signals (241,243,245,341). Different beamlines (212, 214, 216, 312, 314, 316) are established by the modulated light signal(s) (241,243,245, 341) and the mirrors (220, 230, 320, 330) interacting with the absorbing species sample.

Abstract: A spectroscopic method (100) and spectroscopy system (200) therefrom for analyzing samples (298). A sample includes a first chemical component that has a characteristic first absorption peak is provided (101). The sample is irradiated (102) in a measurement waveband proximate to the first absorption peak, and at a first and a second reference waveband where the first chemical component lacks characteristic absorption features. Reflected or transmitted detection data is obtained (103) including a measured power proximate to the first absorption peak and first and second reference powers at the reference wavebands. A plurality of different waveband ratios are evaluated (104) using pairs of detection data to generate a plurality of measured waveband ratio values. A parameter of the first chemical component is then determined (105) by evaluating a multidimensional polynomial calibration equation that relates the parameter of the first chemical component to the plurality of different waveband ratios by substituting the measured waveband ratio values into the calibration relation.

Abstract: Method and apparatus for detecting, by absorption spectroscopy, an isotopic ratio of a sample, by passing first and second laser beams of different frequencies through the sample. Two IR absorption cells are used, a first containing a reference gas of known isotopic ratio and the second containing a sample of unknown isotopic ratio. An interlacer or reflective chopper may be used so that as the laser frequencies are scanned the absorption of the sample cell and the reference cell are detected alternately. This ensures that the apparatus is continuously calibrated and rejects the baseline noise when phase sensitive detection is used.
