  2. Fourier-transform infrared spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Fourier-transform_infrared...

    Such FTIR methods have long been used for plastics, and became extended for composite materials in 2018, when the method was introduced by Krauklis, Gagani and Echtermeyer. [20] FTIR method uses the maxima of the absorbance band at about 5,200 cm−1 which correlates with the true water content in the material.

  3. Infrared spectroscopy correlation table - Wikipedia

    en.wikipedia.org/wiki/Infrared_spectroscopy...

    An infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of molecular bonds and functional groups.

  4. Infrared detector - Wikipedia

    en.wikipedia.org/wiki/Infrared_detector

    An infrared detector is a detector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic ( photodetectors ). The thermal effects of the incident IR radiation can be followed through many temperature dependent phenomena. [ 2 ]

  5. Nano-FTIR - Wikipedia

    en.wikipedia.org/wiki/Nano-FTIR

    Nano-FTIR (nanoscale Fourier transform infrared spectroscopy) is a scanning probe technique that utilizes as a combination of two techniques: Fourier transform infrared spectroscopy (FTIR) and scattering-type scanning near-field optical microscopy (s-SNOM).

  6. Fourier-transform spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Fourier-transform_spectroscopy

    The method of Fourier-transform spectroscopy can also be used for absorption spectroscopy. The primary example is "FTIR Spectroscopy", a common technique in chemistry. In general, the goal of absorption spectroscopy is to measure how well a sample absorbs or transmits light at each different wavelength.

  7. Two-dimensional infrared spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Two-dimensional_infrared...

    There are two main approaches to two-dimensional spectroscopy, the Fourier-transform method, in which the data is collected in the time-domain and then Fourier-transformed to obtain a frequency-frequency 2D correlation spectrum, and the frequency domain approach in which all the data is collected directly in the frequency domain.

  8. Spectroradiometer - Wikipedia

    en.wikipedia.org/wiki/Spectroradiometer

    The detector used in a spectroradiometer is determined by the wavelength over which the light is being measured, as well as the required dynamic range and sensitivity of the measurements. Basic spectroradiometer detector technologies generally fall into one of three groups: photoemissive detectors (e.g. photomultiplier tubes), semiconductor ...

  9. Nondispersive infrared sensor - Wikipedia

    en.wikipedia.org/wiki/Nondispersive_infrared_sensor

    A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector.It is non-dispersive in the fact that no dispersive element (e.g a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.
