Abstract: The present invention provides a method and an apparatus for measuring a light absorption spectra which can remove a noise included in a measurement signal, and achieve a high sensitivity of a laser spectral in a good S/N ratio. According to the present invention, there is provided a method for measuring a light absorption spectra comprising the steps of: (i) conducting a Fourier transform of an absorption spectra measured by using a laser beam source; (ii) disassembling in a Fourier space the Fourier transformed signal into a signal resulted from a periodic vibration component and a signal resulted from a molecular absorption spectra; (iii) removing the Fourier component resulted from said periodic vibration component in a Fourier space; and (iv) conducting an inverse Fourier transform on the signal from which said periodic vibration component is removed, whereby reproducing an absorption spectra in a real space.

Abstract: A spectrometer, typically an FT-IR spectrometer, is operated in a continuous mode so that it is carrying out scans on a continuous basis. The acquired data is stored and can be retrieved when a sample measurement is made. This improves the response of the instrument.

Abstract: Fringe counting in a Michelson type interferometer is carried out by detecting when the amplitude of the reference fringe attains a given value eg a zero crossing. Reversals in scan direction are recognised by monitoring parameters of the waveform such as amplitude and time occurence of successive half fringes and identifying a reversal by the occurrence of a particular sequence or state of the monitored parameters.

Abstract: A measuring instrument with a parfocal combination of an ultra-violet to near-infrared (UV-NIR) spectrophotometer and a Fourier Transform Infrared (FTIR) spectrometer is disclosed. The parfocal configuration of metrology tools obviates lateral movement of the sample between two separate measurement instruments. Consequently, the area occupied by the parfocal measuring instrument is reduced. Moreover, throughput is increased because there is no need to reposition the sample to properly align the measurement area for the separate measurements. The measuring instrument also includes an imaging apparatus, such as a camera or microscope ocular, to accurately position the measurement area of the sample. Beam directing elements, such as a mirror and objective lenses, are mounted on a common movable member. The common movable member, which may be, e.g., a linear or rotating turret, moves to properly align the desired beam directing element, thereby selecting the specific metrology mode. In addition, the measurement instrument includes a purging shroud along the FTIR spectrometer optical path to efficiently purge any atmospherical gases that may interfere with the FTIR measurement technique.

Abstract: A spectral imaging method for detecting and analyzing fluorescent in situ hybridizations (fig. 5) employing numerous chromosome paints (fig. 9) and/or loci specific probes each labeled with a different fluorophore or a combination of fluorophores, the method is highly sensitive both in spatial and spectral resolutions (fig. 6) and is capable of simultaneous detection of dozens of fluorophores or combinations of fluorophores (fig. 7). The method of the present invention can be used for the detection of fluorescently painted complete sets of chromosomes and/or multiple loci from a species such as human (fig. 10).

Abstract: A corrective factor is applied so as to remove anomalous features from the signal generated by a photoconductive detector (10), and to thereby render the output signal highly linear with respect to the energy of incident, time-varying radiation. The corrective factor may be applied through the use of either digital electronic data processing means or analog circuitry, or through a combination of those effects.
