    Abstract: A time-domain waveform of a terahertz wave is measured by a method based on time-domain spectroscopy by using an optical delay unit to adjust an optical path length along which excitation light propagates thereby adjusting a difference between a time at which the excitation light arrives at a generating unit configured to generate the terahertz wave and a time at which the excitation light arrives at a detection unit configured to detect the terahertz wave. The optical delay unit is driven according to a first speed pattern to acquire a first time-domain waveform. The optical delay unit is then driven according to a second speed pattern different from the first speed pattern to acquire a second time-domain waveform. The first time-domain waveform and the second time-domain waveform are averaged.

    Abstract: A method is provided that includes receiving and processing a sample signal scan. Processing the sample signal scan includes applying an inner-product operation on the sample signal scan and each of a plurality of eigenvectors to generate a plurality of corresponding coefficients, and subtracting the sample signal scan from a linear combination of the eigenvectors and corresponding coefficients to thereby produce a corrected sample signal scan. In this regard, the eigenvectors have been generated by decomposing a plurality of background reference signal scans according to a singular value decomposition technique. The signal scans include a plurality of electromagnetic signal measurements at a discrete set of frequencies, where each measurement has been taken by a spectrometer system passing an electromagnetic signal through a sample cell including just a base medium (for the background reference signal scans), or both a base medium and a sample medium (for the sample signal scan).

    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.

    Abstract: A transmission quantification approach that is effective at quantifying the concentration of key atmospheric gases, including water vapor and methane, does not require a background spectrum and is immune to changes between background and absorbance spectra. By using local minima and maxima in transmission of a target gas, this approach creates two spectral arrays as long as a single beam input spectra. One of these spectral arrays represents the points in wave-number space that are less absorbing points, and the other represents the more absorbing points. A concentration for a given gas is calculated by determining what reference concentration creates a residual after division by a pure gas spectrum that forces these two arrays to converge.
