  2. Fourier-transform infrared spectroscopy - Wikipedia

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

    Fourier transform infrared spectroscopy (FTIR) [1] is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas. An FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range.

  3. 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 ]

  4. 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 ...

  5. Nano-FTIR - Wikipedia

    en.wikipedia.org/wiki/Nano-FTIR

    The schematic representation of a nano-FTIR system with a broadband infrared source. 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. Infrared spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Infrared_spectroscopy

    Infrared spectroscopy is also used in gas leak detection devices such as the DP-IR and EyeCGAs. [8] These devices detect hydrocarbon gas leaks in the transportation of natural gas and crude oil. Infrared spectroscopy is an important analysis method in the recycling process of household waste plastics , and a convenient stand-off method to sort ...

  9. Photoacoustic spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Photoacoustic_spectroscopy

    Photoacoustic spectroscopy is the measurement of the effect of absorbed electromagnetic energy (particularly of light) on matter by means of acoustic detection. The discovery of the photoacoustic effect dates to 1880 when Alexander Graham Bell showed that thin discs emitted sound when exposed to a beam of sunlight that was rapidly interrupted with a rotating slotted disk.
