  • Patent number: 7944556
    Abstract: A spectral image is corrected for optical aberrations. Tissue is exposed to a high-intensity, narrow band of light. The narrow band of light is scattered by at least one analyte in the tissue. Raman signals are optically collected from the scattered light. The Raman signals are directed to a wavelength-separating device. The Raman signals are detected as a function of intensity and wavelength to create the spectral image. The spectral image is corrected for optical aberrations using a software algorithm to spatially reassign intensity. The software may be adapted to use a reference image to make dynamic corrections. Fluorescence signals may also be collected.

  • Patent number: 7911598
    Abstract: Components (30) in the interior of an EUV lithography device for extreme ultraviolet and soft X-ray wavelength range are cleaned by igniting a plasma, adjacent to the component (30) to be cleaned, using electrodes (29), wherein the electrodes (29) are adapted to the form of the component (30) to be cleaned. The residual gas atmosphere is measured spectroscopically on the basis of the plasma. An emission spectrum is preferably recorded in order to monitor the degree of cleaning. An optical fiber cable (31) with a coupling-in optical unit (32) is advantageously used for this purpose. Moreover, in order to monitor the contamination in the gas phase within the vacuum chambers during the operation of an EUV lithography device, it is proposed to provide modules configured to initiate a gas discharge and to detect radiation emitted on account of the gas discharge. The contamination in the gas phase can be deduced from the analysis of the measured spectrum.

  • Patent number: 7898649
    Abstract: A measurement method of measuring a spectroscopic characteristic inside of a scattering medium includes a first step of measuring the spectroscopic characteristic of the scattering medium by using diffuse optical tomography by irradiating light into the scattering medium, a second step of measuring the spectroscopic characteristic of the scattering medium by using acousto-optical tomography or photo acoustic tomography by irradiating light into the scattering medium, and a third step of making an assumption of a distribution of the spectroscopic characteristic inside of the scattering medium and of changing the assumption such that a difference between a predicted value of the spectroscopic characteristic derived from the assumption and a measured value obtained in the first step can fall upon a permissible range. The third step uses data obtained in the second step for at least one of the parameter: an initial value, a constraint condition, or a boundary condition.
